I have someone who bought a nice breeding pair of Blue Swedish and one additional black Swedish hen from me. At least I thought it was a hen because I thought I saw it being bred and they were molting so didn't have a curl. However I'm told by the new owner that the black "hen" is trying to breed the Blue hen. I know the breeding pair are male and female because they started the group of Swedish I now have. Their question is whether to bring the black Swedish back and trade with another Blue Swedish I have that I no for sure is a hen or add another hen for the Black Swedish. My instinct is to switch the two so there would be one drake/2 hens but maybe 2 drakes, each with their own hen would be ok with the Swedish. any thoughts? They are in about a 1/8 acre of space.
