Hi - I have been the lead person to help at my kid's science and tech school to hatch eggs for the past three years. I would love to have my own coop, but can not due to HOA. so, I get my chick fix each year by hatching them in the classroom. For the past three years we have been using a Little Giant tabletop styrofoam incubator with the circulating fan and automatic egg turner. We are in colorado and the humidity indoor is usually about 5% so I have a really hard time keeping the humidity up. Our yields have been between 50 to 60%. (it always makes me sad to see the eggs that candled OK but did not hatch...) This year we may be able to buy a better incubator depending on the cost. I would love some advice on a good tabletop incubator (at least 20 eggs) that is reliable and has a good viewing window for the kids. there are so many different bators out there that my head is spinning trying to figure this out. thanks!
