I am getting 4 pekin duck eggs tomorrow, and possibly 8 mallard soon... Any tips or advice about hatching ducks? I would really be tickled if I ended up with a couple ducklings staring out of the incubator at me! Too many questions to ask... Ummm, is 28 days the norm for all duck eggs? How often can you candle? I have only hatched button quail, and will be setting the pekin in the bator with 2 doz button eggs and 2 dozen coturnix eggs(another first for me). Yes I do have a seperate hatcher of course. Just spill and tell me anything and everything that I should know!
