I cannot get our two hens to accept our two 4 week old ducks! Our other two ducks are taking to them fairly well... but the chickens, nope. When I open the little fencing between them the chickens turn into ninjas, jumping on them, ripping fluff/feathers out with their feet and pecking it out. Sending the babies into a screaming running panic. Our other two ducks will fly over the fencing through to visit, ect. Is there any tricks? Tips?
