Hello, I was wanting to ask you all about something that is not fun to talk about but I have to ask someone who knows more than me. Well let me start by saying I have 4 full grown muscovy females/ sisters and they are healthy. This year I introduced a male living with them, and for the first time I let them go broody, my chocolate duck sat on 15 eggs wonderfully and yesterday morning I pulled her out to eat and drink, like I have every morning and I saw a open hole with a little beak. Yay right? Unfortunately no, This is where the story goes south....I came in to check the progress and one baby looked ripped out of its shell, (not near its shell/ not able to move very far yet) and she was pecking at the one on its way out. I thought maybe she is "helping" him get out? Then she did something that shocked me, she grabbed the only one that was out and peeping, and threw it through the air like a rag doll. It's leg was ripped slightly in the ordeal, and I thought maybe she did that because I was in there making her mad. She would like to bite me but instead bit the nearest thing?!...There was only one way to truly know so I went inside and let nature take its course. A couple hours later, I returned and she had eaten the leg's off one, eaten the eyes of the other and both were thrown out of the nest. Also one was half fluffed/dried but had bite marks on its arms and well every where. I could no longer stand by and do nothing so I removed then immediately!...This is truly saddening and hard since this is my first experience hatching anything. What an awful way to go. Another thing to consider is one was under her fluffy and fine, so that confuses me.... Also she is isolated in the coop with plenty of food water and extra space. I don't see why she would do this do you?! Please help I have them under a heat lamp inside, but I am really sad because I thought muscovies were such good mothers and I was looking forward to seeing them grow up under her. Should I cull her? Will she do it again now that they are bouncing around? Is cannibalism in ducks common? Will one of her sisters adopt them? Any advise is better than what I have, sorry to include you all in my drama, I just need help. Ps, the rest of her eggs hatched later that night and they are the ones in the pic.
