Hi, I'm new to the forum. I just received an order of chicks a few days ago. I have several different breeds. One of the breeds seems to continually have a "messy bum". I wash their bottoms daily to avoid pasting. One chick in particular from this breed seems to be straining during defecation and making this loud chirping noise while doing so (discomfort?). I saw previous posts regarding using plain yogurt to help. Should I be really concerned about this? And is there anything else I can do?
