A young cat managed to get into our chicken run at evening; most of the chickens had already gone inside the coop, but one was still out. The cat was desperately trying to escape, running back and forth, and scared the one chicken terribly. I don't think he harmed the chicken, but after we got him out, the chicken wasn't acting herself. At the time we didn't think a whole lot about it (we had checked her over for injuries) so we put her in the coop with the others and closed the door for the night. However, the next morning we found her just sitting on the floor of the coop in the far corner. She didn't get up when we let the others out, or try to get away when we picked her up. Concerned, we checked her over (again) for injuries, but didn't find any. After some research, we figured that she was in shock. It wasn't cold out at all (in the 80's at night), but we brought her inside anyway. We put her in a box with some hay in a room with dimmed light. She occasionally moves, but not walking around. Her comb was very pale and she only makes the saddest clucking noises. She wouldn't drink or eat anything, but we set out some food and water anyway. That was Thursday morning....she still is acting the same, though I have been able to get her to eat some tomato and yogurt. I haven't seen her drinking any water, but I'm assuming she's had to. I've been dripping water onto her beak, and she'll drink that (the poor dear is going to hate me if she pulls through...); it just doesn't seem like enough to be living on. She is a four month old White Marans. I feel so bad for her, but don't know what else to do? How long can a chicken be in shock? Any suggestions would be very much appreciated.
