I had a good hatch, only 3 or 4 that did not develop completely. It seems like everyone had problems with humidity at lock down from what I'm reading...I am not an expert by any means and there are a thousand opinions on these forums, but I think humidity at lock down is quite important. The best thing I ever did was buy a warm air humidifier from the drugstore. This was my first winter hatch and the weather in No. Central Florida certainly kept me on my toes, but after a few nights I figured out how to adjust each day. I know the experts say to set the temp and then leave it, but I'm thinking that winter hatches require a little tweeking on a daily basis. I had to turn my incubator temp up at night and lower it in the morning. The humidity was fine throughout and I only had to turn it on low a few times to keep the humidity between 35% and 45%. Once I hit lock down I cranked the humidifier and it was between 65% and 75% until finish. The temp did not waver as much but still required one adjustment after a particularly cold night. I don't know if that will help the Florida folks who are relatively new to hatching or winter hatching, but that is what worked very well for me. I love this forum and all the info from other people, but also remind myself that some things I have to follow my gut on (such as tweeking the temp each day)
I think that since I only hatch for myself, sometimes for friends, I will keep to hatching in the spring or hopefully to a broody this coming spring!
