Can you keep chickens in an urban area?

[ParsleyCake]

I hear crowing in the mornings, so I know someone nearby keeps chickens, but is it allowed? Can you be made to get rid of the chickens if they are noisy? We live in a quiet suburban area

I was under the impression that roosters are different from chickens?

My nanny keeps suburban chickens, but only ladies.
And she shares their eggs with me, so I am all in favour

A crowing rooster in the wee small hours would be very annoying indeed.

We keep lady chickens, as we just love them for their eggs and as pets. No males though as of course the noise would be awful for neighbours and us
