For the total numbers of hairs, the gray ones have their own hold into the numbers. The suicide rate among them would be on the rise with hatching chicks lol.Go for it,,, great experience for the kids,,,, and you don't have enough gray hairs yet....LOL... hatching eggs drives me crazy trying to keep everything right and hoping for the best,,, swear lose alot of sleep come hatch time,,, especially when they need help coming out !
I have a batch due to hatch around the 10th, hoping for the best, but, expecting some complications as usual.
