We had a Mallard/Pekin chick pip yesterday, it was in the smallest egg out of the whole incubator. To be honest I shouldn't of set that egg and I have known that the whole time, but I had to try. After this duckling piped I decided to make the pip a little bigger for him. As soon as I did his whole beak came thru the opening in the shell. That's when I knew he was to big for the egg. I waited to see if he would get out be himself but by the evening I knew it was hopeless he couldn't even get back in the shell enough to start working at getting out. So I got to work, and it was clear that he wouldn't of gotten out without help. My question has to do with the fact that he had a little yolk sac attached. Its not big, maybe the size of a penny? It's hard to tell because the membrane? Is still attached to his bottom ( which I excpected it would be ) also he is missing feathers on his back and a few other spots. I am guessing it is because it was so tight in his shell. Since it is only in spots where he was against the shell. He stayed in the incubator over night be hasn't fluffed out or started walking. I also believe his yolk sac has broke!Should I be worried?What should I do to help him? Thank You!!! I will try to post a picture soon!
