I went out this morning to feed and make my setting runner get off of the nest. I found an egg outside of the crate that she was in and assumed one of the others laid it. (As they decide to drop them whereever they feel like). I picked it up and there was a crack and a tiny little beak MOVING. Somehow it slipped through the crate (metal not plastic). I opened the door and mom of course was mad but I picked her up and 3 more had little holes. NOW WHAT????? I am thinking I will just let nature take its course but am a bit worried that the other ducks may try to reach in and grab a duckling. Oh, should she remain on the nest (literally) while they hatch? She and I are both new to this.
