I'm also wondering about integrating 4 one week old Buff Orpington chicks with our 2 Buff Orpington hens in their coop outside. One of our hens has been sitting on her infertile eggs for 3 days now (it seems like ever since we showed her the chicks in our kitchen).
If we do decide to give her...
We bought 4 Buff Orpingtons chicks 5 weeks ago. (They are now 5 weeks old). We got them to have as pets, to enjoy fresh eggs and to have fun with our kids. They were supposed to be female, but I'm pretty sure we have two roosters. They act more aggressive and have markedly prominent combs...
