Wow, you had to replace your entire flock? Did something happen, or did they all age out? I had to start with a new flock, but I only started with half, now I'm hoping to add a few more every few months. Good luck with your quest for pullets!!Thanks!!! I am very happy with the turn out. I cannot even get a better hatch with my incubator.. I need about 20 more pullets to hatch out this spring so I can replace my old flock
