Hi everyone! I am a first time chicken owner with chicks that are around 2 weeks old. We got them from a local feed store. I am trying to wrap my head around pasty butt. I've read about it and looked at pictures. What I am seeing with my chicks is poop sticking to their little fluffy butts but it is not blocking their vent area. Is this still pasty butt or only when it's blocking their vents? I have been cleaning them just in case but wanted to clarify. Thanks!!
