Yes you read right! I think I have seen a chicken puke! I was just out in the coop on a matter of a listless chicken. It was standing there, unmoving. After seeing if she would take interest in some bread,(She didn't want any.More strange behavior,a chicken not wanting food.) I picked her up to examine her vent to see if she was egg bound. She opened her beak and out shot some clear,slightly cream colored stinky liquid. I immediately put her down. She seemed to feel better and in fact took a couple steps. She still didn't look her old self though. I left her alone and ran over to the computer. I have read tons of chicken books and have no idea on what it could be! I don't think birds puke...do they?
