Any advice would be much appreciated... I've hatched 6 keets over the last 3 days. The eldest one ('Britney' - 3 days old) has turned evil - she is literally seeking out and biting the toes of the others. She is dragging them across the cage by their feet! This is obviously not good for them or their legs and they are frightened of her. I've purchased peck stop spray, which all the keets now have on their feet. They are under a red heat lamp which is the correct temperature. I've tried putting her in isolation, but due to the cage layout I can only build a low segregation wall as she still needs the heat from the lamp. She was in isolation for 3 minutes until she worked out she could jump over! So she is now back in terrorising the others Any ideas how I can stop her?!
