I have a buff orpington 23 weeks old. I'm new so I don't know how to sex chickens....but it can tell what all of mine are except this one just by behaviours. And well....the dead give away of the crowing! But this one boggles me. Lately it has been laying around almost like I read how they start squatting when they are ready to lay. Kinda stays away from the other. Doesn't crow. Combs and wattle turned bright red. This is the biggest bird in the flock. And to me looks like a rooster, but I think I may be wrong?! Should I be getting nest boxes ready?
