I'm making my first jncubator...quite nervous about the whole thing...but my current question, is: if i have a metal support grate over the water reservoir, can i wrap it in window screen material? So the chicks can't fall through... will that allow enough air flow? ALSO: Will a front/side window work? All the ones I have seen are on the top...but this will be up on a countertop and my little kids will want to see in....ALL the time I'm sure, so I'm thinking about putting a window on the front of the ice chest...so they can just walk up and be eye level with it...any reason why this won't work? Can I do both or will that allow too much heat to escape? I could do two small windows instead of one medium sized one?
