First let me say I'm new at raising baby chicks in the wintertime I've never attempted it before but I have a need to now so I've run into a couple questions on raising and incubating eggs in colder months like December and in January my first big question is humidity in the incubator I have a GQF model 1502 Incubator and I have eggs going in every week and eggs coming down every week or let me say chicks being born every week. When I move the eggs down on the 18th day I try to raise the humidity level on the 19th date to about 75 to 80% and I prefer 80% but in the winter months I've found that the humidity level in my house his droped down to about 40% because of the heat I used to heat the house that's making it hard to bring the humidity level in the incubator up to 80% and I'm wondering if anyone has any good ideas about raising the humidity in a 1502 Incubator up to about 80% where the chicks don't have a hard time Hatching . I guess what I'm asking is there a better material out there to use for wicking then the sponge material that GQF Sales? Or possibly put it in a air pump like in a aquarium with a bar in the bottom of the water tray to create bubbles to create more humidity in the air. My second question is simply this. three week old baby chicks in a brooder box at 75° is that too cool or about right?
