Has anyone seen anything like this? I can't figure out what it is and not sure what to do about it. The chick is making an effort to stand up and move around but this thing is attached to her rear end. I wanted to wait until she was dry to take her out and really inspect but until then does anyone have any ideas? It is stripped but doesn't look look like poop and besides it would be way to much poop for a newborn. Could it be an undeveloped twin?
