Hmn. That is quite a conundrum. Judging by the comb color is hard, since it is fifteen weeks... I would observe. Those saddle feathers say boy, but I am just not sure. My rooster Elrond sits just like that, though, haha! I would watch for a crow at this point. 🤷
I would say it is a boy, as for the sweetness, I would keep hanging out and cuddling with him, but keep your fingers crossed. Roosters can be a mixed bag.
When I have to choose one, I choose one that dances for the ladies! Dancing is an under-bred trait, but I try to breed for it, as it makes for a much more peaceful flock, with the original rooster and his sons.
Huh. If that were so, wouldn't you think it would be caused by any food being prepared? I cook very, very frequently, and I rarely use the microwave anymore.
Whatever it is, the microwave is staying in the garage.
