Can anyone advise please. I have 8 ducks, a drake and 3 female Cayuga and a drake and 3 female Welsh Harlequins. Two of the female Welsh Harlequins reject the drake and when I change the water in their paddling pools these two females 'mate'. The one which is always on top is a silver phase, the other 3 including the drake are gold phase so she looks different as well. The 2 who are rejecting the drake are definitely female. I have 3 eggs every morning when I let them out. I don't have room to get anymore ducks to make up numbers for the drake and he is getting frustrated and the 1 female who accepts him is bald on the back of her neck because she is getting all his attention. What can I do? The cayuga's and WH have separate housing at night but are together in the day.
