I have a gander??? that tore up a drake overnight. Both are removed from the flock of 10 ducks, 3 geese.. The drake is missing alot of feathers on his back. I put Green Goo on him, he is in a stall in the barn right now hiding under a pile of hay. The gander is in my garden shed until I figure out what to do with him. Everyone has gotten along until lately. All I raised last summer from babies. 10 ducks, 3 are drakes. Geese 1 for sure gander, 1 possible gander, 1 goose. They have a huge enclosure. Plenty of room. 8x15 nice enclosed shed overnight. Should I separate all ducks from geese?
