I have a hen that has been looking a little subdued for the past few days and yesterday when I let the chickens out she got knocked over in the rush to exit the coop. When she looked a little dazed I pulled her out and she is in a kennel in the garage. She was eating and drinking yesterday. This morning when I checked on her she seemed really cold. I am going to bring her into the house but what concerns me the most is when I picked her up to dip her beak in water she vomited bile. Right now it is leaking out of her mouth and she does not look good. She is my one of two Wheaten Ameraucana hens and I would love to save her!
