Hi- I am writing this for my husband, who is the raiser of the chickens.... We have about 30 chickens, mostly bantys and Rhode Island Reds. We let some hens set so we could have some chicks, and they are now about a month old. This is our first batch of chicks in a while, and the roosters and hens are unrelated. Of the approx. 20-25 chicks that we have three indicate a neurological problem. One could not walk at all, he would just heave himself around with no control of his legs. There are a couple more who have some staggering, but not as serious as the other. Can anyone direct us to some possible causes? They get regular chick starter. They are kept in a fenced chicken house and when we are home, they are let out in the yard as often as possible. Thanks!
