I candled my eggs on day 4 and have 6 growing with 2 more iffy out of 15. That's better than I expected, considering the circumstances. I'm going to candle again in a few days to be sure, and then I'll remove the bad eggs.
Since my last post, I was told that my roo is a black tailed white Japanese Bantam, and the hen is a bantam EE, so these will be mixed breed chickens. If they make it to hatch day, they will be my first chicks from my own eggs! I had 2 eggs under a broody that were at day 24, with no pips, so I finally cracked them open, only to discover that one died early on and the other died around day 15. Sad. I'll probably try the broody route again, but not until next time.
