What breed is this

[Mmz]

Hi guys I was just wondering what breed this is. I hatched him from a mixed batch of hatching eggs. I was also wondering if its pure breed or hybrid if anyone knows thanks in advance

What are the breed options? Possibly White Marans or White Orpington. Could maybe be a White Bresse also, but the body type seems a bit heavy than the norm. All these breeds are decently uncommon, so knowing options is a must!

Chances are good it's a crossbred. The breeds @Rhodebar Lover listed are possible but are fairly rare.
