OK I'm in probably my 5th batch of chicken hatches so I've got my routine down pretty good. I've got a regular customer buying chicks as fast as I can hatch them. He has now asked me to hatch a few ducks for him too (he's supplying the eggs) so far from what I've read I should be able to put the duck eggs in about a week prior to the chicken eggs. Then fill it up with chicken eggs and all will hatch together. I have had better hatch rates with higher humidity here so that should help the ducks from what I've read. Also I've read my chick medicated layer will be fine for a week as I wait for him to come get them from me. So am I missing anything? I can just drop them in the same brooder together and all is well.. Or am I missing something? Any input will help as I've never hatched a duck!
