Hello, I am pretty new to incubating. I just wanted to get some thoughts from some experienced incubators out there. I am also new to BYC and love this site. My question is I have my incubator in a coat closet. There is no vents in this closet so the temperature of the closet doesn't fluctuate very much. I thought that would be a good place to put the incubator. There are holes in the top of the incubator so it can get air. I have a Hova-Bator 1602N with a fan and egg turner. I am just concerned with it being in the closet with the door shut is it getting enough fresh air.I read in my manual that came with the incubator that insufficient oxygen can kill or hurt your hatch. Should I open the door? I have been leaving it about half way open. Also, the temperature moves in between 99.4 and 100.4 is that ok too? Am I ok to shut the door or should I leave it open? I am currently hatching 11 English Lemon Cuckoo Orpington eggs. I am on day 3. Any advice would be great. Humidity is between 45-50%
