OK so we have a coop in our garage that we built to put our Buff Orpingtons and their rooster, a Splash Cochin, in. We have had and still have two young pullets in a brooder box in our house, since it's too cold outside for them(right now). One is a black EE(with possible Bantam in her), named Raven. The other is a Bantam/Buff Cochin, named Pumpkin. They are both very small for their age. Raven=about 6 months, and Pumpkin=5 months. We plan on putting them in the garage coop with the two Buffs and their rooster when it gets warmer out and when they get more mature(their voices haven't even changed completely yet, even at their age!). So one day we took them out to their future coop to meet the flock; now I used to think that Buff Orpingtons were melow and gentle and friendly....they are, but boy do they get mad and aggressive with new chickens on their coop! Caramel, one of the BOs, tried to attack Pumpkin while I was holding her, by jumping up and trying to peck at her! And when Raven or Pumpkin get near either of them, they both start puffing up! It could be caused from their broodiness....They have both been acting broody, just not serious about it....so maybe they either: (1. want to sit on Raven and Pumpkin, like they are their own(puffing up...etc.) or (2. they are grumpy because of the broodiness, and they are protective of their space. Or it could be something else? We decided not to put them even near each other, to see how they acted it! And the rooster kept dancing around; I knew he would try and mount them at the first chance he got...even though he is soooo big compared to them! What can we do to get them used to each other easily??? We want them to be friends, and not to peck at each other all the time! Pumpkin and Raven don't know anything about getting pecked at. They are a little scared of the BOs and the rooster, too. I'm afraid that they will get hurt badly if left alone with those older chickens. Thanks!
