I have a 7 month old barred rock that was totally healthy yesterday. I came home from work today and she was alone in the yard "sleeping." Tonight she didn't go into the coop and when I went to coax her in, she was laying with no muscle tone and breathing heavily. She ate tomatoes yesterday and my sister said she heard they are toxic. Is it the tomato or the plant? She has had NO symptoms until today and I am totally stumped but I doubt she'll be with us in the morning. I worry that what ever got her might get my other 2. Any ideas or suggestions?
