I woke up this morning and looked in on the silkie's brooder, to find a bunch of blood! It's not like a few drops, but it's all over. The poop is like all red. I think it's from sully, but chatterbox tends to poke at it so she might have whatever it is too. The feed store is closed today, so I can't go there, but what do you think the chicks have? How can I treat it? Will they die? Please Help!
