They are doing great. We currently have 45. we lost 1 because it escaped the brooder and ended up under our quail cage unnoticed. 1 other one struggles to walk well due to developing curled toes on one foot - Vitamin E deficiency since the embryo stage I think. The rest are great though!

Glad to hear that (but sorry about your losses). 45 is a pretty good number, I think!
