I noticed that two out of three green legged hens I have, are limpin from one leg, one worse than the other. The one in the worst condition limps and the leg look as if she can not articulate her fingers and like if they are just stiff; from time to time she atempts to bend them and so she does but only up to a limited range. The other hen is the same exept that she limps much much less and the only thing afected apears to be a finger which seems like it is stiff also. I dont know if it is my paranoia but I'm on the impression that other chicken with in my flok show this signs as well but in a way that you have to look good or it becomes imperseptible to the necked eye, like if they were about to go into the same condition my other two are. Any sugestions as to what it could be and how to fix it. Thanks.
