I posted recently about a crowing pullet in the Behaviors forum. Well, I'm hearing her crowing outside now, and it's almost midnight! I thought she just was hormonal pullet, top of the pecking order, no roosters around, crowing. But at night? When she "crows", she looks uncomfortable and she's been getting progressively more lethargic. That's how I would feel if I were hormonal -- however... Now I'm imagining air sac diseases, or tumors, or... I don't know what to be afraid of! Please help me understand what could be causing this. I won't sleep well until I do. Thank you for any advice you can spare.
