I just received to Auracaunas and two White Rocks chicks last Friday (day old chicks). They are 5-6 six days old now. I can not tell which chicken or chickens are doing this, but there is a poo that is watery that is dark reddish-brown, and it smells BAD... Now I know chicken poop isn't pleasant but this foul (no pun intended). I've tried to sit and watch which chicken is doing this but the poop I watch it normal looking and I've seen normal looking poop come from each breed (I think), so I know it is a specific chick just don't know which one. They are on medicated feed. They are all active and acting happy. The only concern is this poo... Should I watch a see if things change good or bad? Could this be a specific breed thing? Could this be a sick chick? I'm scared/concerned. This is my second round of chicks (my other girls are 33 weeks and all different breeds with poo that never looked like this). Help?!?!
