I'm illegal, and i only have 4 girls. i got them last spring as chicks and they are now 8 months old and doing great!! they are also very quiet....with the exception of Audrey and Cricket singing the egg song when they first started laying....they don't even do that anymore. So, i'm getting 6 more chicks this spring. But that will be IT! lol....seriously though, i think 10 is enough for me in my situation. they free range in my entire back yard, which has a 6ft privacy fence. So, my question is, if you're illegal, how many chickens do you have? And how long have you had them?
