Q, if you where asking opinions on humidity and temp ill tell ya what I do. I dont worry about humidity to much (55%+) I typicaly run around it 30-40%. I just put some water in and if its in that ball park I let it go.The only time I worry about humidity is at the hatch as I dont want any babies drying in the shell and getting stuck. Best way to avoid that is NOT opening that bator (during hatch) wich I find hard to do at times. Ill get the humidity around 50% (for hatching day 18) or a little more and when the chicks start hatching it will shooooot way up on its own. So as long as my humidity is 30-50% during incubation I dont worry, i only add water if its below 30%. If adding water doesnt work take a clean sock, soak it in hot water and toss it in the bator. I dont think there is a magic number but I dont let it go below 30. Ive had some great hatches when i fussed and cussed and worried about humidity and ive had just as great of hatches as when I let it do its own thing and just let it go. Many times ive had chicks hatching in my cabinet bator and the humidity only runs around 30-40% in there and they hatched without getting stuck . On your temp mine usualy run around 100.5 ive had them average 102 and didnt seem to make a difrence, higher than that and id get worried though. I like the temp right around 100-101 that way i feel like I can be off a degree either way and still be ok if the themometer is off.
