I've been through many ups and downs learned a lot of the ins and outs of the incubator. The temp spikes, drops, poor ventilation, too much humidity in this humid climate!!!!But, I've yet to have a broody hen. Finally one of my older girls, laid her last two eggs in her clutch and plopped down on them. I can't get over how well she sets!!!! I have to make her get off the nest for food and water. Anyway, it's nerve racking. I keep wondering if I've got the right temp lol guess I don't need to worry...this time!
