Our old Sussex's sister was killed by a fox, so I bought a nervous Rhode Island cross as her companion. They got along fine, but then the Sussex got run over.
The 'poor old' Rhode Island looked a bit lonely - she was an ex-free range farm chicken who used to live in a massive flock - so I bought two bantams as company for her.
Since then, she has turned from a nervous bird into Godzilla. They are fine together at night, and fine when they are free-ranging, but in the morning before I let them out she bullies the little ones mercilessly. We keep the pop hole of the box open at night in the summer, but she won't let the bantams out into the pen if she is there - she pecks them until they go back into the box, meaning they can't eat or drink till she gets let into the outside area.
We are due to go away for a few days next week - should I get the RIR a separate coop, and is there anything I can do to stop the bullying? We've had them all together for 10 days so far.
