I got two Black Australorps and two Americaunas, today, 4 and two weeks more or less. There were probably 20 chicks in a 2 x 4 box, the Australorps both have missing feathers and red raw looking skin. The Americaunas look fine. Is this just normal feather growth, overcrowding or something else? I can't see any creepy critters, so should I just wait and see? They are now sprawled in their new home eating, drinking and pooping normally. Really enjoying room to spread their wings.
