CONGRATS!!!! Sounds Great!!! I only lost 1 chick out of 67 to drowning. He pipped on bottom and was not rolled onto it! They all should be fine! Some use the egg carton method to hatch. I just let them lay in the bator floor. They all hatched! but the 1. of course. Get the brooder warmed up, feeder, waterer, paper towels down, feed spread on top of towels, marbles or stones in waterer....etc
Good Luck and God Bless!
