So yesterday we noticed we had one dead bantam in the brooder. It was fine most of the day and then all of a sudden it was dead... And this morning all 4 that we had left were fine running around and everything was fine eating and drinking and now she's not moving barley opens her eyes and I try to sit her up and she just flops down.. She has shallow breathing. I took her out of the brooder as well as the other chicks and they are all separated... What in the world could cause this?!? Please help!! I took a picture of the poor chick :/ her name is freckles. I'm really sad about this!
