I don't really see all this frailty everyone talks about. I hatched out 75 and at 3 weeks old I put them in a grow out pen. The temp is in the high 50's and 60's. I have a heat lamp on one end of the pen but they quit using it and just do what nature calls them to do, covey up. I lost 3 out of the hatch, from piling up on one another I suspect. This is the first time I have hatched bobwhites and the seem very hardy and active to me. I don't even go around them much except to give them clean water and feed. They do drink a great deal of water, I was kind of surprised they drank so much. I never gave them any sort of medications just an electrolyte additive in their water and 28% protein game bird feed.
