I have a question and observation for the experts here.
I noticed in these two hatches, in both bators I had pips on day 19 and several hatches on day 20 and every one of these were from one rooster and his hens.(majority hatched 20 days) Both of the first ones out in each bator were big yellow chicks from him(I get red, yellow, black and barred). My other rooster and his hen's eggs hatch later, most on 22. Not one of their 10 eggs hatched before day 22, actually and I had two that hatched on day 23. I read so much about temperature and that lower temps tend to produce later hatches, higher=early. But, they were all in the same bators at the same temps. So, is it because the early ones may be stronger? (even though all are doing well) Or, maybe just genetics, like some chicken's individual genes may produce earlier hatches? BTW...both coops are the same breeds.(Black sex link to black sex link) 11/12 hatched in one bator, and I am looking at 18/18 if this last one pipped gets out ok.

I attribute the success to all I have read here on BYC. (I don't want to give the numbers for the shipped eggs, but I will 3/8 ring neck pheasant, ZERO/8 Midgets

, 3/18 Dorkings.... Sigh
