I had cockers next door that were grandfathered in in middle of city to raise gamecocks, that would toss out losers of one way of another for hawk bait etc or just to slowely die of injuries starving n cold in winter.. well the ones that lived would come over to our condo because a neighbor on other side fed songbirds and them letting sleep on their balcony. They hardly crowed and feral cats another neighbor down way fed, kept them and songbirds in check. Well I asked manager if I could keep some hens in my yard space if just made look good to get some fresh eating eggs and hatch them for school children etc. She said that was fine, so I got waaaay into getting different kinds and colors etc, n eventually had to cut back to bantams as they are technically not poultry,for show and pet class, that won that case against city and property owner. Before getting rid of production type chickens though, I trained them with a chicken sounding shriek that said to hide, that they eventually did whenever heard new people coming. Pigeons btw are supposed to be protected under migratory bird act and a few other official presidential decrees signed into law, if they are banded especially, or free flying (which I'd do releasing when city inspected, and said they'd just have free fliers shot etc if I didn't call them in to be taken and put down, because trained sort of like chickens where I'd just release, because the city said if they were able to seize before my court order went through, they could charge so much daily for how they would hold, or put them all down that to next day and charge me for cost of (so sadly I got bitter and battled wits with little city I was in until higher authorities could take over, because when sent city away first two times politely but knowledgeable, they then had city workers come out to shoot etc n seize my animals illegally, to which I shot back and released my dogs when I'd leave after planting cover everywhere. Point being fighting city officials is ultimately a loosing battle in long run unless you boot corrupt ones out with sheer force of numbers. So if your going to keep him for now do it low key, maybe get Velcro straps to make a "no crow collar", and lobby to right higher officials with signed agreements from neighbors to keep poultry foul etc in some way under acceptable conditions.. it smoothes the road and then neighbors won't get jealous because you have chickens but they are to scared because it's illegal or they are misinformed about non existent health risks compared to normal urban pets and wildlife, proven promoted by commercial poultry industry and extermination industry (one housecat housemouse or parrot is much more "potentially" dangerous than having a dozen chickens or hundred pigeons). Other point to look at keeping him is, if he is Rhode island red, he may get aggressive once hormones kick in (these can be stopped before starts by holding on back in arms like a baby stroking softly, petting n rubbing etc).
