This is my second time incubating Australorp's. The first time was with Buff Orpington's and the Buff's buzzed on out of the eggs, the lorp's were slow to come out, on day 22, pip to zip took forever, and several didn't make it at the last minute. This time I am doing a straight run of Australorp's and it's like dejavu. Only 2 of my 18 are pipped and struggling to make it out and the rest nothing and we're at day 21. Anyone else have a hard time hatching Australorp's in an incubator? Just wondering if they are a more delicate breed to hatch because those Buff's were totally different. Thanks!!!
