I know I am supposed to wait 4- 8 hrs before taking my chicks out, but only 1 / 6 hatched so fare and can see the others starting its moving around and I am afraid of it bumping the thermometers in to other eggs. I read opening the incubator to get the chick out reduces the number of birds that hatch, is this true? what should I do? it keeps peeping and some times sounds like its screaming....
