We are new here, we hope you made it through, its been a month or so since your post.
Our 9 year old will quote the city code word-for-word if anybody questions "Is it OK to have chickens in the city?" I really, really hope your town's city code allows for chickens. Ours includes a sentence"...except for birds and fish" when it forbids livestock. Our city code also bans "the sale or giving away of artificially dyed chicks", which sort of implies that residents sometimes have chicks.
We have overheard 2 local residents say "Who do they think they are with chickens in their yard", but we also receive visits almost daily from curious and pleasant neighbors.
Oh we hope your pet chickens are safe and sound in your loving care! Good Luck, please let us know how its going!
