We have 4 ducks (2 ancona 13 wks,2 cayuga 9wks) and live on a lake, where a few houses down from us have a few diffrent breeds of domestic ducks. Their is one duck from the pack that keeps going after one of our cayuga's but not our other 3 ducks. I dont understand why or how to stop it. It it because maybe its a male going after a female? We dont know the sex of our ducks yet. Or really sure how to tell the sex. Another question is our ducks dont or wont go in the lake yet. They have a baby pool in our yard that they use daily but wont go in the lake. They will lay down by the water but wont go swim. I think its sorta crazy and it could be that i baby them with a clean baby pool twice a day. Wonder if i take the baby pool away if they will swim in the lake? One more question.... how much do you feed your ducks, we feed them a grower food twice a day but they act like they are straving. Any help would be great. Thanks!
