I have three drakes that are one year old. They were hatched together and lived peacefully as brothers for 11 months. One day the Alpha started bullying the other two. Within a short amount of time the other two quickly turned on the Alpha and started bullying him. I’ve had to keep them separated within the same coop as I put a divider between them so that they can’t attack. I let them out separately to swim, run and forage. I tried letting them out together every day but they automatically jump on each other and start fighting. The strange thing is they hate to be separated! They talk to each other and stay together inside the coop if I let one out he will stay by the coop hoping that the others will come out to “play”....as soon as they are all free they attack What should I do? Will this stop?
