Actually chickens are a bad idea unless it’s a commercial venture. The expense, mess, cleanup, upkeep etc isn’t worth it based on the fact eggs are relatively cheap if that’s what ya want.
My relatives are happy with their chickens.
The rooster is optional if the neighborhood has noise ordinances. But I find a melodic crow when I should be getting out of bed anyway far preferable to incessant barking.
The egg production is just a nice bonus to the sheer enjoyment these feathered creature will give you.
