To all the people who have the skills to build their own incubator: To keep it short, I had a broody hen, I ordered eggs for her, they will probably arrive tomorrow, I messed up today and I spooked her out of the nest. I have no idea if she'll get back on. I don't have the time to build an all out incubator for these eggs that will be arriving. Will it work if I set up an old cooler with a small pan of water, a rack for the eggs to sit on, and a heat lamp inside? Or am I SOL? Thanks!
