I have two darling Orpington pullets nine and 10 weeks old. They are buff and black. I wanted a cuckoo colour for my third and the only girl I could get is about 36 weeks old and laying. I got her two days ago and she is literally enormous! I thought Orpington’s were meant to be friendly but she has been pretty brutal towards the two pullets when we tried free ranging them together…pecking out their feathers and eating them! So we split the coop and the run into two separate units for them to sleep and I’m letting them free range separately. I have had mixed advice about this but some are saying the pullets need to be at least 18 to 20 weeks before I free range them all together so they can defend themselves with the inevitable pecking order. This is rather inconvenient but doable. I have also heard that if you keep them in the same vicinity but separated like this so they get very used to each other that it minimises the aggression with the eventual pecking order. Any advice about this would be really appreciated. I am new to keeping chickens and my supposed docile cuckoo orpington seems more like Mad Max the last two days! She also bok bok’s very loudly at dawn! She is sweet on her own though
She arrived after an 18 hour poultry truck ride and was starving so I imagine stress being in a new space may be part of it. Thanks in advance
