I have 2 Australorps that I have had about 2 weeks. I noticed today they are having watery poop. What can it be?? Is there something I need to do. It has soome of the normal coloring to it but watery. I feed them layer pellets with small amount of crushed corn. They have oyster shells available. The water has a teaspoon of ACV per gallon. I do feed some scraps. They have just started coming out of the coop and run to eat scraps. Yesterdays scraps were steak cut up in small pieces, potato salad and baked beans. I don't think they got much because they don't really like eating with the cat. I can see a little sticking to the feathers but not much. I just happened to be in the coop today when I heard one of them poop. I don't see any worms or anything. Please need advice !
