can any one tell me what breed they are?

[JustBabyMargo]

Looks like my blue maran cross did. But he’s barred now because he is a barred rock x blue maran or a blue maran x cuckoo maran.

That's not a true muff. That's what I refer to as a baby beard, it goes away as the chick grows.

Cockerel, australorp/brahma cross bred.

He could have other breeds mixed in as well.

It looks like a Lavender Orpington Brahma cross.

He’s not lavender, but he could be an Orpington cross.

He's bearded so certainly not just Brahma x Australorp. I would wonder if Marans x Ameraucana or Easter Egger would give you a similar outcome...
