We have a leghorn that was born first in a batch of three and has always been the "alpha" of the group. Both our boys have thought they heard "him" crowing but are not certain because it wasn't exactly like a classic cock-a-doodle-doo and they were in the house when they heard it. We also have crows that live in the trees around us and they can be very loud and obnoxious at times, so it's hard to rule out that the boys might've heard that. Anyway, we're thinking our beautiful/handsome Leghorn Cochin might be a he, but we're just not sure and we're going to have to be away for a week while in-laws stay at our place and take care of them. What behaviors are dead giveaways if I've never heard him/her crow? Can you tell just by looking at this age (11-weeks)? It seems I've seen pictures on the web of leghorn hens that have just as big a crown as ours, so we're really uncertain.
