I got varying advice each time I rang the council so we did what we could within that advice and hope for the best for the bits that don't fit. We're lucky that where we live we're not surrounded by houses, so the spot they are in should not bother anyone. Each District Council seems to have different rules for suburban chickens and not all of them make sense.
I learnt the other day that we could have a sheep! What we would feed it I do not know, but I found it odd!
