Okay, I'm new to the whole chicken thing. I have two 4 month old hens, neither are laying yet One, seemingly overnight, obtained a tumor looking growth on her comb. It seems to be getting darker by the day, she's has had it for about 3 days now. She's acting normal, playful and energetic, poop looks normal in colour and consistency. It is really hot here, all I'm not sure if that plays a factor. Any ideas???I just can't decide if I should be worried or not yet.
