Well, my chicks will be 5 weeks old on Wednesday, and as of yesterday, when I moved them to a new, larger pen, I noticed strange behavior in one of the BAs. The chick will do fine, walking around, pecking the ground, etc., and then will just fall over, and push itself along on the ground, with wings out, or flapping, and the chick sort of half rolling around on the ground. It almost looks like the chick is trying to take a dirt bath, except that the "episode" seems to render the chick unable to get back on it's feet while having the attack. When I first saw it, I thought the chick was just trying to take a dirt bath. However, it was odd enough that I had to have a closer look. While the chick is on the ground flopping around, the others walk on it, step on it's wings, etc., and I was able to go right over and pick it up while it laid there not moving (usually they run from me if I try to pick them up). After a few seconds, the chick snaps out of the attack and goes back to walking around like nothing happened. Today I noticed that, while it was flopping around, it craned it's neck around and under it's body, in a very contorted way, and after the episode was over and the chick stood back up, it continued to tremble and shake it's head and shoulders (sort of like Kathryn Hepburn used to do in the final stages of the disease she had). Do chickens get epilepsy? If not, what would you think this problem might be, and what should I try to do about it? Much thanks in advance for your help/advice.
