i got a lil giant Forced Air with egg turner i also got a old one that i will use for hatching. I have some questions on them. The temp needs to be set at 99.5 degrees is that for incubating and the hatching temp? chicks hatch in 21 days correct? And i will be hatching barred rock chicks when do i candle the eggs? To the set the humidty in the incubators it has 2 line fills on the side and one in the middle do i fill both and do i fill both in the incubator im hatching in? they also have the 2 red caps i do remove them at any time? the incubator im using for hatching is a still air one and i will just place the eggs on the wire rack do i need to do anything special to that incy i no to the place the eggs in that 3 days befor hatch? Thanks for your time
