My 2 chicks are 9 weeks old now, and getting pretty big. They seem to fight each other and their mum for food these days. She still sits on them at night though. When can I take her away and put her back in the main run with the others? Am I best waiting til she stops sitting on them at night? I'd really like to get them separated in the next few weeks so that I can get her back with the others and so that the chicks can go off to their new homes. Any advice appreciated!
