My young seabright hen just suddenly couldnt walk about a week and a half ago. I've been successful raising her from a small little chick for 6 going on 7 months. It did get really really hot three weeks ago here in Oklahoma. I had some company over and the 12 yr. old girl was helping me in my backyard, when one day she pointed out my seabright and said "look she is hurt". I picked her up, no sign of injury, no bloody stool, nothing coming out of her nose, perky as can be, just can't walk!!! So i eparated her out of the free range flock (i have an area about 100 by 100 feet)...in a big special cage outside so she could be by her friends outside, but no one would stress her. Then I realized she was going downhill, eating less, laying more and more on her side. So I realized she needed to be taken into the house (out of heat). I went to local store and got some electrolytes thinking the heat might have gotten to her. But her companion roo is doing great. Its been a good solid week insdie the hosue. Now she is almost laying limpless. she perks up once and a while trying to move around in the pet carrier. have her on shavings. She is no longer drinking or eating. I can't get water down her throat w/syringe...OH.... some little bantees her age have started laying. Someone told me she probably needs oyster shells in her diet just as soon as they start laying. I've successfully raised Cockatiels, over 20 years, so I know how delicate some birds can be. a new chicken friend told me how delicate these Seabrights are! Gosh, I just found out she was a seabright only 2 - 3 weeks ago! this is soooo weird! must be illness of some sort... I'm quickly reading up on as many threads here as I can here. Help.
