I have a bunch of chicks that just arrived on Saturday morning. This morning I was cleaning off their behinds (a couple of them had some poop stuck on it), and when I looked at one of my RIR I thought it had a lot really stuck, but when I cleaned it off there wasn't much there but it did have TWO openings there. Has anyone ever heard of this??? Is that a problem? Is it a defect that I don't want in my line of birds? Should I notify the hatchery? It seams to have a larger bottom then the rest, but w/ two shoots I guess that's why. Any advise would be appreciated! ~Thanks
