I have a drake only flock I had to rehome my females because of the noise and I don't have enough space for the right ratio. I had a flock of 2 hens and 3 drakes and they were together for about 4 months. After I rehomed my females my dominate male has become the outcast the other two seem to stick together and chase him around and mate him in the pool. He also looks like he is loing weight. I don't know if getting rid of the females affected him or if it is drake hormones in full swing now. I'm still trying to figure out if drake only flocks work or not. I can't seperate the bully because I have two picking on one and the two bullies dont really pick on each other. I don't want to rehome my loner because he is the nicest most friendly in my flock. I know I didn't give you advice but if I figure anything out ill be sure to post it.
