This is so cool! I'm happy for you to have a huge flock like this.
I'm always in the hope that other people can and successfully do have large flocks for the hope that it means all of us can get away with having more of them. It doesn't make sense to me that the limit on poultry is the same as for cats and dogs, with city ordinances.
...
But I guess for your thread question, I have to ask, how far are your neighbors? And are you on the edge or in a city?
I want to ask also how common is it for people have more than 10 birds in a city? (I am hoping that 10 to 20 can be done in the city without being noticed, by others. To me it seems you'd actually need this many if you were producing daily eggs enough for a full family living there.)

Now I have 7 ducks and 19 chickens.
Our ordinance states "as many as can be properly housed and cared for without creating a health hazard or nuisance ".
There is their out if they choose......nuisance=one person complaining.
