I have a 10wk. old chick that I saw take a couple of sips of water and then walked over to the feeder and threw up the water. It wasn't alot but should I be concerned? I once had an adult chicken that did this when I first got her and I took her to the vet and the vet said that it was a sign of worms. This chick and all the others have been eating medicated chick starter. I don't have to worm them do I?
