I'm having a hard time telling if my Blue Andalusian is female or male. I'll call her a "she" since I've treated all my chickens as hens from birth hoping that none would turn out as roosters. She has always been independent and preferred free ranging. She is vocal to get out of the run but once out doesn't make too much banter. She doesn't have a high pitched crow but I'm wondering if she is actually crowing and I'm just thinking it's hen talk. The last four days she started picking on my Cuckoo Marans who just started laying eggs. She has pecked a sore in the top of her head. Someone told me this is male breeding behavior. Any thoughts from the photos posted would be helpful. Thanks!
