My first time raising baby chicks, I still have a lot of questions. Okay so when I got my baby chicks, my little roo (about 1 1/2 week old) always had a pasty butt, and I always got it cleaned. But now every time he tries to poop he always kinda cackles louder than normal. I always check his booty/vent when he poops and there is nothing there, it comes out fine.. What could be causing this & is it normal? He walks around/sleeps/ and everything fine.
