We have 3 chicks that are 2 1/2 weeks old--1 of them has very solid, almost dry looking poops. The other 2 have very watery, dark brown, very stinky poop. Like super stinky dog poop. It doesn't look bloody to me. We have been holding them on our laps with a towel under them, and when I use a wipe to clean in up, it just looks like a thin brown smear. They were vaccinated for Mareks and have been on medicated feed. Looking for suggestions, things to look out for, etc. Thanks!
