My call duck eggs just pipped this morning and are shaking around and in the process of hatching. The cochin hen foster mommy has gotten off the nest though, and doesn't seem to want to sit on them anymore now that they are moving. I put her back in the nest and she is settled down at the moment, but if she gets up again, is it very bad? Should I move them into an incubator? I have a cruddy little giant incubator I could start up. What would you do???
