What breed is this?

Hiya, while on a day out at a fun park with my kids today we found a chicken that we really loved and want to get some eggs as I'm setting again this week anyway. I asked 1 of the workers and was passed round about 6 different people till I got to speak to the person responsible for them and the highly informative answer I got was it's a cockerel! Either I'm going mad or thats the sex not the breed, lol. I think it's a Brahma but just wanted to make sure.
The largest one

Thanks in advance
