4 won't be too bad at all. I have 40 in my brooder right now. Good luck with the Gambel's. I hatched some twice for a friend and did not have very good luck with them....Right now it looks like just the one has pipped... I candled them before lockdown and I think only about 4 total will hatch, but they're certainly taking a while. They're gambel quail, and today is day 23.
