My male is with six females all to himself. Before he was with only one and I've never had any issues with him. The female is sister with the other four hens and unrelated to the fifth female who was the original female with the male. She and the other four are 8 and a half weeks old. The male and original female are at least 6months old. The female in question hasn't seemed very happy as she has desperately tried to escape when i open the aviary, escaping twice but I've caught her easily. When I've put her back in the males immediately grabbed her before I've even hardly let go as if punishing hector wanting to escape. Well today I saw blood on his beak and a bloodstain on his chest feathers so i started checking the females. The one in question as a bloody bald head and a oozing bleeding 'hole' behind one eye, above her ear hole. I immediately brought her indoors. She seems deeply depressed. She sat on my kitchen table with no interest in escape although she will try to move away if you go to touch her. She has very limited interest in food, mealworms or lettuce. She is now in a bird cage resting and sleeping. But does this mean she can't ever go back? I'm guessing there is no reason we can guess at for this? Other than personality clash or she's bottom of the pecking order or she is punished for not submitting to the male?? She could be kept as an indoor pet but if he does it to another female it might be him that has to go? I already have a pen of boys separate to the main aviary. I don't want too many separate pens!
