This year we have gotten alot alot of orders for chicks (first yr shipping) so I decided to try the 2 incubator set up I have heard of some using. The eggs are in my hovorbator incubator for days 1-17 then I move them over to my more high tech full view incuview incubator for lockdown. My eggs looked perfect when going into lockdown, humidity at 70% and temp at 99.5 but nothing happening & today is day 22. What went wrong? The only thing I can think of is I have the temp at 100-101 in the First incubator as its a still air & the 2nd is a fan circulation set at recommend 99.5. Could that temp change have killed them? Should I just match up the temps? Or do I need a circulation incubator for my day 1-17 as well? FYI I have had perfect hatches in both incubators when using start to finish. This is my first hatch trying to rotation idea. The reason I am trying this is I have lost chicks that had zip trouble that I was not able to see in the hovorbator incubator, but that holds 47+ eggs & the incuview only holds 27 eggs. So with the rotation I can hatch eggs every week. Thanks for any help as I very important eggs going into lockdown on Thursday.
