This is my first time hatching chicks on my own. This is my 3rd bath of chicks that I've raised but this is the first I've hatched myself. Only 2 have hatched so far but the older one is pecking at the other. One is 1 day old and the other is 2 days old. The older one keeps pecking near the other one's eye and I don't want him to get hurt or blind for that matter. Should I separate them? They have food and water so it's not a hunger problem. I'm sure this is normal but the younger one is still getting used to walking around and eating so I don't want the older one giving it a hard time. The older one, Uno, is a Sicilian Buttercup/Easter Egger mix and the younger one that's pictured below, Dolly, is a Welsummer/Easter Egger mix. Thank you in advance!
