Hello everyone! This is my first post but curious to see if you can tell if we have pullets. We got 6 Rhode Island Red chicks may 2nd and was told they were between 2 and 3 weeks old. Except they just now look appropriately 4 weeks old (to me). By their "aging" they would be 6.5 weeks old. We did unfortunately lose one baby one the second night. But hopefully the pictures help if you can tell the sex yet. I'd appreciate any idea on the estimate age as well. Thank you in advance!
