Hi everyone! I need a little help. I have searched the internet and my chicken book over to try and find an answer. Yesterday I went to the chicken coop and found my largest rooster just lying on the floor and the other chickens were walking over top of him. I picked him up immediately and carried him to the front porch. It was like he couldn't pick his body up off the ground he just lay there with his mouth open and his eyes kept closing. When he would open and close his mouth it seemed like he was trying to make a sound but he never did. Finally he started throwing up some brown colored liquid with cracked corn in it. I give them scratch on the cold winter nights but they also have laying pellets and plenty of fresh water and whatever bugs they find. They have access to the outdoors. Just a medium size fenced in lot. He hasn't been acting himself for the past few days anyway but I just thought maybe he is getting old. I don't know his breed and I don't know how old he is. I just got him probably about 4 months ago from a lady. I am concerned because I have my hens in the same coop along with two other roosters. He did die last night. Please help me!!! Also the back of his comb looked a little purple. There coop has a chicken light in it but it has been very cold here in Tennessee.
