I have bought baby chicks to raise before. But this is my first time breeding, hatching, and raising right from my farm. These chicks had wing feathers at 2 and 3 days old. I never noticed this in the other batches I've purchased in the past. In fact if I remember right, it took a month to start seeing feathers. These are a week old, and they all have wings now and some have tail feathers. Is this normal? Or are they advancing due to cold weather changes? . Thanks for any info.
