It wasn't a hatchery in Jax, we were picking up shipped chicks from McMurray. I don't know where Orange Park is at but we found a fantastic local hatchery in Newberry. His birds are big and beautiful, they lay well, and he has about 20 breeds available. Along with the chicks we got shipped from McMurray (Columbian Wyandottes, he doesn't have those available), we picked up some Salmon Favorolles and Rhode Island Reds from him yesterday.
So now we have 24 chicks in the brooder, and we should receive our 15 turkeys later this week from McMurray. And 39 is plenty in our one brooder box. We also have 20 muscovies coming, so that's going in our other brooder box.
Chicken math has extended to other poultry too.
