Guest guest Posted April 22, 2004 Report Share Posted April 22, 2004 Granted this study is in Africa, but it is interesting. MOST birds there are free range, and so you would think they'd be healthy, but from this it sounds like they have a rather high mortality rate. And parasite rate. Stuff to think about ... we've never had a high mortality rate among chicks but they are kept inside for the first few weeks and have plenty of food. Also they had a high rate of parasites, which is something to think about if you like raw chicken liver ... -- Heidi Jean http://www.fao.org/ag/againfo/subjects/en/infpd/documents/econf_scope/add_paper1\ 1.html In Tanzania, Permin et al. (1999) examined 600 live chickens and found the presence of a range of diseases. All animals were parasitised with one or more (up to 14 species) species of endoparasites. In total 29 different species were detected in the study. Furthermore, 65.7% of the animals were parasitised with Cnemidocopt-es mutans, Dermanyss-us gallinae and/or Echidnopha-ga gallinacea.

My first thought was, " One man's 'free range' is another man's 'That's not healthy for a chicken!' " We had a neighbor down the road who's pheasant's were " free range " - inside an enclosure on bare ground without a single blade of grass, where generations of birds had been raised for years. But I went to the article and took a look: " The majority of these animals are kept in free-range scavenging systems, where the birds scavenge around the house during daytime. " Unless the house is VERY large, that is not enough room to roam about and not make the earth barren from the waste, let alone to support the birds in bugs and greens. Speaking of which, greens weren't mentioned anywhere in the diet of the birds. " The mortality is believed to be caused by mismanagement, lack of supplementary feeding, predators and diseases " That pretty much sums it up.

Speaking of which, greens weren't mentioned anywhere in >the diet of the birds. My understanding is that most birds are *loose* during they day, and maybe penned in at night. So they have plenty of room. And likely plenty of greens, depending on where in Africa and what time of year. > " The mortality is believed to be caused by mismanagement, lack of >supplementary feeding, predators and diseases " > >That pretty much sums it up. LOL I don't know what they mean by " mismanagement " but for my birds, they have had LOTS of room to roam and they still need lots of extra food. And the predators really do take a toll, once they figure out where the chickens are! It's not just chickens ... I've known several people with large ponds, and once the eagles and herons found the ponds, bye bye fishies. It's the " disease " part I wonder about ... there are lots of wild birds so you'd expect there'd be plenty of parasites around. Which probably doesn't hurt them much, as adults. But in another article it was saying that they lose a lot of chickens in those parts of the world due to Newcastle disease. -- Heidi Jean Quote Link to comment Share on other sites More sharing options...
Guest guest Posted April 24, 2004 Report Share Posted April 24, 2004 We could discuss this forever and not get anywhere since we don't *know* what the housing situation looks like. What comes to my mind when I read " scavenge around the house during daytime " is not a good situation. Our birds scavenge around the house and way, way beyond the house. No one would call it " scavenging around the house " as that's only a small part of where all they go, for a small portion of the day. True, these could be lush situations and they just don't supplement their birds' diets, or it could be these are more like low income situations with housing close together and lots of competition among all the flocks for food. We don't know. You see it as green. I note that the researchers do not mention any greens in the birds' diets. I don't see why you wonder about the disease part. Any time an animal is undernourished disease has an edge it doesn't usually have. I guess I just don't understand what you are thinking this study tells us. I don't think it tells us anything applicable to anything outside of right there where the research was done. Not unless we knew a whole heck of a lot more.

Not unless we knew a whole heck of a lot >more. > >Rhea Well, mainly about the parasites. I had one chick that seemed to have symptoms of a parasitical disease ... it has been inside under a brooding light, but it had some greens from the yard. I was reading up on chicken diseases, and it seems to be the case that a lot of chickens get sick from wild bird diseases, whether or not they are in good health. I went to the coop for some advice, and they guy said, " wow, I've had more people with parasite problems these last few years. We NEVER had parasite problems " . Now, most folks around here let the chickens wander. It's a very green and lush area (always! except maybe for a month or two in fall when it might get dry). But, the winters have been getting warmer, so the worms survive in the soil better. Now, in the tropics and in a lot of Africa, it is VERY warm and there are a LOT of parasites and diseases we don't get here. But some of those diseases ARE beginning to come here (like the mosquito borne diseases that never were seen here before). You are right, we'd have to read a whole lot more to get more info, and I've been asking around to folks who have chickens here. Among the folks who leave them loose all the time, they have a very high death rate. However, they often replace the hens every year anyway, or they just let roosters loose in an orchard to eat the bugs and don't worry much about if they survive or not. A lot of the deaths are likely from predators. Anyway, I just sent that article in case it was interesting to others. Every area of the country is different. I have been feeling guilty because 2 years now, we've lost 5 chickens out of 17 or so, but now I find this isn't odd (at least around here) ... if chickens are loose, often they have a high death rate. Again, depending where you live! The first year, we had 5 die in a month apparently from something they ate ... they got listless and stared spacily, next day they were dead, not all on the same day, but spaced over 2 weeks. I locked them up and no more died. But I don't know what they were eating. The next year a coyote started hanging around ...again, we locked them up for a bit til the coyote went away. The chick, BTW, didn't turn out to have parasites. It seems to be ok now. I have no idea what the " answer " is ... I just post data! I like having the chickens out wandering, they've been weeding our garden and clipping the grass and they look nice wandering around, and they certainly enjoy it. I suspect in this area we'll need a combination of being loose and being locked up. Alse we need to deal with the " crow " issue ... they've been hanging around and stealing the chicken food. -- Heidi Jean Quote Link to comment Share on other sites More sharing options...
Guest guest Posted April 26, 2004 Report Share Posted April 26, 2004 Folks - It is a standard assumption that chickens that have been bred for meat or chickens that have been bred as layer and chickens that have been bred for both laying and meat, need their 'free range' diet subsidized by grain at the rate of at least 30percent of their daily intake. Birds that do not have this supplementation available will not prosper and will most likely not be healthy. Chickens are not wild birds, not by a long shot. They have been being bred and managed by human beings since before the Roman empire. Thats a long time to be removed from nature. Sure, they need more 'real food' in their diets, but, due to their genetics, they need feed from the farmer, also. -Allan Who really loves his flock of 100 Barred Rock hens Quote Link to comment Share on other sites More sharing options...
Guest guest Posted April 26, 2004 Report Share Posted April 26, 2004 100 hens? Wow! I'm curious...if one wanted to get 12-18 doz eggs per WEEK from a flock, how big should that flock be???

When I had hens I had then loose in the yard to forage during the day. I also fed them wheat, barley, and alfalfa seeds, which were sprouted before being fed to them. In the winter I used green hay for their bedding, they ate a great deal of the hay. They were given vegetable scraps and the some of the pulp from juicing too. They seemed to do well on this diet.
