Greetings! I have one muscovy drake and three scovy ducks. The drake and two ducks get along well, hang out together. The third duck seems to be increasingly isolated from the others, keeping her distance. This morning, she didn't even come for treats when everyone else was there, she just hung back in the bushes. (No, she was not laying.) Do the others hate her? Has she been rejected rather than just being the low ranking duck? Thanks in advance for your input.
