I agree with that! With as warm as we start getting earlier in the year, the chick's hatched later have more time to adjust to the swing's in the weather before it start's getting too hot.A lot of chick raising advice for the rest of country may be timed wrong for us in AZ- especially Phx metro. In Phoenix (and even up north near Prescott since I have a large greenhouse) I would take advantage of the weather conditions and place a chick order at the shoulders of the hatch season (like first thing and last thing - avoid shipping in summer). We are in one of the few places that can raise chicks better in fall (or even winter) than in spring. Just my opinion.
My Bielefelder rooster is doing his job so I can start hatching my own over here now. The other day I set 4 of the egg's from my flock for testing and when I candled them they all had the little spider thing growing in them. Yes, one of the egg's is from the NN hen as I still have her here.
