Any ideas on what breed?

[quackquacks]

We took in these chicks at 3days old, they are now 7 weeks. We have a guess what breed they maybe but as we are fairly new to the chicken life would like some opinions from others that are more experienced. Also we think we have two boys two girls what are your guesses to gender to please? Pictured aren't the best, they would obviously keep still an pose for me hahaha.
Many thanks in advance xx

Looks like Dark Brahma cockerel and pullet. Buffy is a Borris.

Imagine the white bird is Leghorn cockerel.

You have 3 cockerels and one pullet. Not sure on breed of the white ones, they have blue legs.

Huh, I missed that photo of Nugget. Yeah, two white cockerels. Also missed the slate legs. I must need more coffee! Not Leghorn. No idea what "breed" as I doubt they are Breese.

I think they're all cockerels... where did you get them?

From a rescue centre who were unsure what they when we took them at 3 days old.
The reason I put this post is because the last couple days I been thinking poss 3 to 4 boys xx

They're likely mixed breeds too then. The White ones in theory could be White Marans, but being uncommon, paired with the others looking like mixes, it seems highly unlikely
