I had a chicken die last Saturday. She never really developed comb or wattles. Her comb was always white. I thought she was sickly from the got go. I've had the chickens for four months. Now, another one has a pink colored comb but has that "look" of sickness in its face. Still eating and poop looks fine. Will the others die? It's too cold for coccidiosis isn't it? I don't want to lose my egg layers. Only two out of five are laying. Not sure what to do.
