I have had my broody in a pen within the main chicken pen for 3 weeks with her 3 week old chicks. I wanted to see how she and the chicks would react with the rest of the flock so I would know if I needed to buy all flock feed or if I would have problems and have to keep them separate for longer. I set the broody and her chicks in with the rest of the hens and she seemed to be protecting them by puffing up her feathers and spreading her wings but then one of the hens pecked her and jumped on her back, then when she got away she abandoned her chicks for a few seconds then went back in to try to get the chicks away from the other hens, she got pecked again and ran, while the chicks went through the fence to the other side. None of the other hens pecked the chicks but isent the broody supposed to be the one beating up on the hens when they get too close? I have seen her attack one of the new pullets that is low on the pecking order. I dont know if I can trust her to protect them or not. Also, I have a rooster I was wondering how he will react to the chicks as they grow up or when he finds out there are new roosters, I will be getting rid of the new roosters as soon as I know which ones are roosters.
