Here's a question for everyone, I had 3 duck eggs that tried hatching but couldn't. They had broke through the membrane but never made it to the shell and died. The parents are free range ducks so they shouldn't be lacking anything nutritional. I live in WY and the elevation is about 5,700...
When you hatch out eggs on the bottom, do you let them lay on their size or put them in egg cartons? I had the styrofoam bators and have moved up to a cabinet bator. I have an Isbar due to hatch today sometime.

They are on the website still. I haven't witnessed my pair mating yet even though she is laying. In another week I'll start checking for fertility.
They came from Ideal Poultry in TX, so they aren't show quality but I still like having them around. I live in WY so we have more winter than summer, its hard to have them because they make such a mess of the water. :(
