Okay, so my chicks have all been doing great, eating, drinking, growing, and feathering in really nice. I have a Rhode Island Red chick that is 4 weeks old and was doing fine Saturday. Yesterday evening, I went to feed and water them and he was laying on his back and couldn't get up. Picture a turtle on it's back and scrambling around to right itself and you will see what I mean. He had a right proper little hole in the shavings where he was trying for all he was worth to get up, but couldn't. There is no sign of a wound or where the other chicks may have injured him and he will eat and drink, if we hold him upright, but he can not right himself, much less stand. If he gets on his back, he kicks and squirms, trying to get up, but he simply can't. He is currently in my office, propped up in the corner of a box so he doesn't have to lay on his back. Chirping rather loudly at the moment. I have given him a few drops of Poly-vi-sol vitamins and made sure he eats and drinks. Is there anything else you would suggest?
