Has anyone experienced longer hatch rates with Orpington eggs. This is my second time purchasing eggs and the first group only had 2 hatch and this group so far has none. I purchased 15 eggs and then filled the rest of the incubator from my own hens. I have had 12 hatch of my own eggs and more cracked. The breeder is telling me that they take longer to hatch than 21 days. Has anyone experienced this?
My lav orps are usually late day 21. I've had them go longer. Only earlier if I run the temp higher.

Might get more in the spring. I can recommend a breeder in NY to get chicks from, but not eggs. Chicks are the better way to go usually because pea eggs are so fussy and hard to hatch even without being shipped.
