I have some BCM, showgirl silkies, and sizzles set to hatch on Jan 6th. I have a GFQ incubator and I LOVE IT! Last year I used the LG and Hubavator incubators. I did like the hubavator, it gave me WAY better hatch rates then the Little Giants. However, the LG'S were still air. Thru trial and error over the 100's of eggs I have hatched I would say your hatch rate depends most on how reliable your bator is. The stryos seem to flux way to much, and tend to spike the temp more often then they should in my opinion. If your buying a bator, a fan is a must. They cost more but will save you money in the long run. Your hatch rates will be much better, I know because I had a total of 6 stryos running at once.
The dry hatch is not a good idea in my opinion. I believe the chicks will not be able to zip properly if they do make it to hatch day. I am not really picky about humidity, I just fill my water container in the bator and let it run. Before lock down I put a diaper into the water to help boost the humidity, it seems to work perfect for me. My humidity during days 1-18 runs between 20-40 then up to 50-60 for the last 3 days.
I know some humidity is important during incubation. Think about it, if you have ever had a chance to pick up a broody hen off her nest you will see the eggs will have persperation on them from the hens bottom sweating. Humidity is a part of the natural incubation process. I know some people do dry hatch and succeed, but I am not willing to risk it on my expensive eggs.
Anyway, I am very excited for hatch day......this is my first hatch since back in August
Good luck everyone, please post hatch day pics if you are able.
