I'm on my 2nd hatch, at day 7. I candled at day 4, as well as today. All 12 CL eggs that were viable on day 4 are all still developing nicely. I will candle again on days 14 and 18. Expected hatch day is the evening of the 28th, but I anticipate I'll be sharing a birthday of the 29th with the majority of the dozen!
Best of luck to all of you!
