I have 4 female rouens and 2 males. I just noticed today the bigger of the males is chasing the other off. This may have been going on for a day or two but not much longer.At night they are all in a 4x8 duckhouse together. During the days they are in a 50x 100 fenced in yard. I was thinking about dividing the duckhouse but looking for ideas. So far not noticing any damage to the smaller male but still has me concerned. Was looking to see if anyone had adult rouens for sale to possibly get 2-4 more females as I think the duckhouse has the space as well as the yard. Just not finding adult females which I would imagine is difficult this time of year. Any suggestions? Thank you for your time.
