YIKES!!! I heard all kinds of sqwaking and my roo was screaming, and I ran out of house to find a squirrel INSIDE my Momma/chick Tractor. Momma is going after it like white on rice, and the squirrel of course is going nuts tearing around till it finally gets out the way it came in. It dug a hole under the frame and was trying to get the chick feed. Anyway, 3 of the chicks all have eye injurys, one looks like the eye is complety out, just hanging.....I'm thinking the squirrel scratched them whilst spasing out trying to get out of there. The chicks are running around and eating and drinking like normal, and I've cleaned up the eyes and one beak the best I could with warm water. How do you know if a chick is in pain or not? And will they adjust, I mean one will probably only have one eye, and perhaps 2 will only have one eye. The third one is swollen but it looks like the actual eye is still intact.
