I lost my Gander to a coyote and the hens were so sad that I got them a new one. I was told that they would be happier with a Gander. I made sure to get a docile breed, he's a well-bred Buff (see photo) who has just turned 1yr. old. I have 4 hens, 3 Embden and a Gray/Pilgrim cross and he was fine with all of them until recently when he got his hormones and began mating. He has rejected one of the Embdens, she's the middle in size and is in the middle age-wise too. He has kicked her out of the flock and is very aggressive with her if she comes near them. Does anyone know why he would do that?, she's (Angelica) sweet, loving healthy, gentle and now my poor girl has been forced to take up with the Runner ducks. I think I need to re-home this Gander, he's causing so much upset. Angelica misses her flock and they miss her.
