22 week old Barred Rocks and no eggs so far! Waiting is killing me. Two of them started squatting yesterday, so hopefully it will be soon. They are getting Purina Omega 3 pellets, egg shells, treats. Am I doing something wrong or is this normal? They free range, but they don't venture very far from the coop and I have been searching the area. We open door at 7 am and close it at 8 pm.
