Hi I went out to my chickens a couple hours later than I usealy do to give them water and check on them. They seemed very thirsty since it's cold and dry out. One of them has a lower voice then usual and it sounds kind of craky. Do you think she has a cold or do you think her voice just sounds differant because of how dry it is outside. Also one of my chickens throw up on the grownd after drinking a lot of water. It was just clear throw up which makes me think she just drank to much water. Help would be appreciated. thanks for reading.
