Oh dear @FeralUnicorn - I am flabbergasted at the number of 'nay sayers' who are trying to dissuade you! Particularly in view of the hoohaa and furore of a few weeks ago when eggs were in short supply. What could be more natural than having the means and wherewithal to produce your own, rather than having to go to a shop and buy them? Go for it, say I, if you are permitted. And if your neighbours have kids, get them involved and on board - most children love collecting eggs. My lodger's little boy, when he comes to stay, derives enormous simple pleasure from helping to clean out my chickens, feed them, collect the eggs and then (whisper it!) have them for his breakfast, fresh as a daisy and straight from the hen. How natural is that? And chickens are fun, delightful to have around, have their own endearing little personalities and the noises they make are very soothing, apart from the occasional 'how clever am I, I have just laid an egg' clucking. And even that is infinately preferable to barking dogs surely?
Noisy, smelly, destructive, produce lots of waste? Bit like humans really then, only far more useful.
But I forgot - anything natural which has the capacity to impact, no matter how lightly, on humans is treated with suspicion, distrust, dislike, almost fear and lothing; be it ' weeds' in the garden (AKA wildflowers growing where they are not wanted), ants, wasps, spiders, mice, beetles, bats - you name it and people will want to destroy, kill, remove or eradicate it. Are humans, surely the most destructive, pointless and useless species on the planet, so important that everything has to make way for them - even keeping chickens is now considered anathema to many it would seem
Go for it OP - after all, you are not considering keeping guinea fowl or peafowl ( which, yes, because of the racket they make, could be considered unneighbourly), despite being beautiful birds. Are you...?
