Hello! I haven't been on BYC for a few months, but now that I am starting to post again, I have a few questions about hatching my first batch of chicks. Currently, I have 3 Barred Rock pullets, 1 RIR pullet, and 1 RIR cockerel (was supposed to be a strictly laying flock, 3 BR and 3 RIR pullets, but one was lost during shipping and the roo was a mistake. Now I am glad, though, because I can hatch and sell my own chicks!) They were born early May and all started laying around early November. Would it be wise to hatch eggs, even though they are still relatively young (they haven't had their first real molt yet, so it could be any day, and I want to kind of have a reliable source of eggs to hatch so I can pick the best ones.) Should I let them molt or just go ahead and start incubating soon? I live in the north, so I was thinking if I collected eggs and started incubating mid-March, they would be hatched and in the brooder early-late April. I would probably sell them when they are a month and a half (late May-early June) or so so they are started and I have a chance to reasonably guess on the RIR chicks genders. I would sex the Black Stars, of course, right after they hatch. Would the BR pullets or RIR pullet hatch the eggs? Or should I incubate them (I will probably do this anyway, as it will still be really cold) I would like the need to know facts about incubation, as I have absolutely no experience with hatching. What I do know: you have to keep the tempature and humidity at an extremely precise level, you can only wait up to a week of storing the eggs before you have to put them in the incubator, the hatch rate for non-shipped eggs is about 80% (which is about what mine should be, more or less), eggs take about 21 days to fully hatch, they start to pip around 18 days, eggs must be turned three times a day up to day 18, should be candled about a week after entering the incubator for dead embryos. Anything else that is extremely important? I will post questions as I think of them. Thanks to everyone who helps!
