My 4 chicks are now 7 wks old. I have 2 LF and 2 bantams. At first I thought it was only one of the LFs that was dropping the very loose poop. She's at the bottom of the pecking order and gets picked on the most by the dominate one. I rationalized that it was from fear she was doing this. But I saw that the dominate LF does it too. I've been feeding them chick starter, chick grit, and rolled oats. What could be causing the very wet droppings?
