Wow! That is a great guide even though it was written with chickens in mind, not ducks. It basically matches everything I've read over the years about assisted duckling hatching, though she's far more emphatic about avoiding assisting unless absolutely necessary than in anything else I've read. It must have taken her a ton of time to put that guide together.
I've never been in a situation where I've needed to consider assisting, and I've never had an egg pipped at the wrong end, but I'm very grateful to have this for future reference. I really wish we could save favorites inside this site in our profile or something. I have so many bookmarks at this point in Firefox about ducks that I sometimes have trouble finding them even though I I try to keep them carefully organized.
Thanks, Enriquec (and Sally) !
