I have no regrets with our chickens, but we have a bit more space.
That said, we discussed it with the neighbors on either side. We did get an accidental rooster which one neighbor liked the sound of - one wasn't that crazy about it. We rehomed him due to his being too big for our silkies, then ended up rescuing a silkie rooster just a couple weeks ago. He crows more than the other roo, so we're hoping it doesn't become an issue.
One thing I didn't realize was how loud the HENS would be. Sometimes they seem to alarm at nothing and all get going. Sometimes it's the egg song. Sometimes it's just one hen. But they are LOUD. And we only have 7 hens.
Soo....in a small space with close neighbors that's a definite potential issue. I'd make sure anyone in ear shot is not going to complain, and that you're allowed to have whatever number in that area. If you get chicks, have a plan if you end up with one or more males.
I adore my chickens and it was bad enough to get rid of the one roo (and he went to my sister so I still see him now and again). So you don't want to be in the position of raising them and then having to get rid of all of them if they're not legal or if issues with neighbors come up or the maintenance is too hard. We made adjustments - I've spent a ton of time outside at 20-30 F, in the wind, scraping away snow so my chickens can have dirt to scratch in and move around or just supervising while they roam the yard. It's worth it to me, it gets me outside, but it's not always fun at 5am before leaving for work. We'll have to train our pet sitter for the chickens now, too, not just cats.
Hope you get to bring in an animal that meets your needs and that you can provide for long-term. Crossing fingers for you.
