Hi everyone,
I have just been reading these posts from page one up through 7 then skipped to the last page. I may have missed a little but thought I would give my opinion. First off, I think we each need to see what works best for us then go with it. I have a web site with an incubation page and a hatchling page and have some of my last hatches listed on them. First off I want to say that my dad was born in 1897 and mom in 1905. My dad was 51 when I was born. Last of 12 children. My parents always had chickens but never hatched with incubators. They always hatched with broody hens. I started using incubators early last year. My first few hatches were absolutely disasters. I've tried the dry hatch, different incubators etc. I then tried to work the incubators like dad used to say about the old hens. He said if you watch an old setting hen that could free range she would leave the nest on the mornings when the dew was on the grass and get her belly feathers wet and go back in and get on the nest. she would almost always hatch out almost every egg. Sometimes they would steel their nest out in the field somewhere and we would think that something got her and after a few weeks here she would come with a bunch of little biddies following her. What a site to see. Dad would make this little triangular hutch out of slats and leave about 4 inches off the ground so the peeps could get out and run around a little but the hen couldn't drag them to far till they got a little older.
Right now I have 13 RIR eggs, 6 Barred Rock eggs and 3 English orpington eggs in my Brinsea which I keep the humidity between 40 - 50 % then on day 18 I candle them and all the good ones I take out and put them into one of my styrofoam bators for hatching and my humidity is usually between 73 - 77. My last few hatches have been 85 - 90% and these are all shipped eggs. I will keep doing this way unless my hatch rate goes down. On my own eggs that I've put in with shipped eggs I've had 100 % on fertile eggs.
Please, I don't want no one to think that I'm trying to burst any bubbles with this post but this is what works for me and I think a lot depends on the bators, where we live, what kind of heat you use in the cold weather etc.
