We raised hatchery chicks, chicks that I incubated, and had hen incubated and raised chicks last summer. The hen raised chicks grew feathers in faster, flew and roosted sooner, but seemed to grow slower.The chicks I brooded were fed chick starter, and the hen's chicks were offered chick starter, and ate whatever mom found for them while free ranging. The naturally hatched chicks learned how to forage from day one, and were already flock members, where the hatchery chicks had to figure it out, and be introduced after they outgrew the brooder.
