I'm fortunate enough to have my home on land and pushed back far enough that no one complains about the roos crowing. Sometimes its best not to have a rooster because you can get very tempted into hatching some eggs of your own. Having three well let's just say I may or may not have just bought an incubator last night.....haha
I thought chickens would be addictive because when I first got them for the backyard I wanted every breed there was to be had. However, one trip to the vet with a sick bird cured me of wanting too many. Glad I'm zone restricted to 5 hens only or I could've been tempted to suddenly overrun my backyard! I lived on a 25 acre farm and even then we restricted poultry to 50 Babcock Leghorns and only a dozen Pekin ducks and Toulouse Geese. The horse, cows, goats, and sheep were too much trouble but poultry was a whole lot easier. The horse ate too much, the cows always needed milking twice a day or they moaned awfully, the sheep were always butting us, and the goats ate everything in sight -- bicycle tires, hand tools, tack, wood fences, laundry on the clothesline, vegetable garden, you name it and they damaged it! Poultry turned out the easiest farm animals to manage.
