Hello BYCer's, I am getting worried something is running through my flock. A couple days ago I notices a chicken who couldn't use it's left wing. It was getting picked on so I asked a friend to foster her. I thought she must've got stepped on by a goat. This morning I noticed a two month old chick can't walk. My friend who was fostering the first chicken called me this morning saying her conditioned worsened and she can't walk now. Another 2 month old has been limping on a foot for a while now and I thought it must've got stepped on by a goat also but it also seems to be getting worse and not better. I have been checking out my flock and there is nothing visibly wrong with any others right now but I'm worried there is something they are passing around. Any knowledge or suggestions are greatly appreciated! Thank you.
