I have one cross breed egg in my incubator - (silkie dad/EE mom) it piped internally two days ago, but has not yet piped externally yet. it was moving slightly this am before I left for work ... but it was doing the same thing last night when I went to bed. not sure what to think. We haven't had good luck with these cross-breeds - with most not hatching (quitting around day 10/15). (we actually only had one hatch successfully so far under a broody - I put this one in the bator after the hens had a dispute and broke two of them around day 10 based on candling) I've hatched before, but honestly don't recall how long between internal/external pip. I've never really paid much attention. The problem here is i don't know exactly what day it's on because I was away. When I candled, I noticed it had piped intnerally (was chirping ). This is the last one - and my son has already named it and knows it was chirping two days ago. He (and I !) are getting worried ! Should I help it to pip externally when I get home ? What do you think ?
