Hi all! I'm a first-timer, just got my chicks! The breeder wasn't sure on their ages cuz they were hatched at a local school. I think I have 2 EEs (brown and white), one Buff Orpington, one Australorp, and one Barred Rock. Any opinions on that? And any idea on age? And when might I be able to take an educated guess on genders? We got 5 but can only keep 3, so hopefully at least 3 are pullets! Thanks everyone!
