Bigger chick pecking at smaller chicks???

[My3ChicksMBD]

Hello!!! Hopefully, this is the right forum for my question I have three chicks. One of them is noticably bigger than the other two chicks and that one keeps pecking at the others. Why is he? He'll go and peck at their heads. He doesn't do it every minute but sometimes often. Should I separate this chick from the others? But if I do, I think that the others might chirp because they think the bigger one is their mom. I'm not exactly sure if they think that but they seem to stay close by that chick. Does anyone know what I should do? Is this a common thing? Thank you!!! ~My3ChicksMBD

Are they all the same age? Or are the smaller ones newer? Take a look at this, too: https://www.backyardchickens.com/a/a-guide-to-understanding-the-chicken-pecking-order It may help with this.

When I got the chicks, the guy said they were all a week old but we realized that the bigger one had wings and seemed older than one week. So, I think the big one is a bit older. I got them all at the same time. And thank you!!!

Maybe let them see each other but not be in contact. This way they will get used to each other.
