I have not been able to find very much information online about using hatch bags. I have hatched chicks many times, but this is my first time using hatch bags to separate chicks in the 'bator. I thought I'd post here to let other curious hatchers see how the process goes for me. Hopefully it will be smooth, if not, someone can learn from my mistakes. 
Right now the eggs are on day 20, and there are two pips!
