I have a 3-week-old chick that still has its egg tooth... I've never seen that before on a chick this old. The chick is being raised by a broody with the flock and is outside where it has rocks and things to scratch and peck at, so I'm surprised that the egg tooth has held on this long. Could this cause problems in any way? Or is it just a weird chick? I have 6 chicks from that batch and only this one still has an egg tooth. It's growing and feathering out on track, eats, drinks, flutters and acts normal in every way.
