Congrats on your upcoming ducklings. I am living what you may be getting ready to go thru. Our duck hatched 9 ducklings and I had seperated the drake before they hatched and allowed the other hen to stay with the mama while she sat. We have a very large pen so we divided that in half with snow fencing we happened to have. His side had large pines for him to go under and we set up a shelter and has his own pool. The snow fence worked great as he could watch them while being seperated. I had to put the aunt in with the drake after the ducklings hatched because she was being mean. So the mama and 9 ducklings had the side with the coop and they are still seperated at 6'weels. Even at six weeks they almost look full grown but they are still babies with a lot of their behavior so you know an older duck could intimidate them. I tried several times to put them together but the aunt is still mean. The drake was ok, but he's in with her to keep her company. I will continue to try. We had a set back with an injured baby, not related to the other ducks, so waiting for her to continue to recover before trying again. Ducks can just be mean to ducklings so it's great if they can all start out together, but I think the aggression towards ducklings can be pretty common.
