My black cochin has been on 4 runner duck eggs for 23 days. Today while checking on her I noticed 2 had pipped. I was shocked. Not only is it early bit one has blood around the hole. What should I do? I automatically went in the house and fired up the bator but I don't know if I should interfere or not. She's worked so hard for these babies we'll both be heart broken if none hatch properly.
