Hi, I had a 4 week old chick that was fine in the evening than yesterday morning it was standing alone seemed to be having a hard time breathing, was not eating and died within an hour. :-( This morning I when I went out I have a 2 year old Barred Rock hen that is exhibiting the same symptoms.The chicks pen is next to this coop. She is standing in one spot moving very little, feathers slightly ruffled and not eating. Her poop is liquidy and light brown, her comb is bright red. Any ideas what I'm dealing with? I don't think both getting sick is a coincidence. I am going to quarantine her. Thank-you
