Depends why you ask. Are you in the city? Is there a limit by your county? They can all be pets, or like some of us that have big layer flocks and meat bird flocks too just a few are pets.
Right now we are happily owned by 17 hens and 1 roo all are pets and plan to add to the family in the spring ( after reading everyone here say the more the better )
seminolewind...how many chickens can I have as pets?
Depends how big your hallway is. If you keep them outside, I don't consider them pets. Right now I have 6 hallway chooks, with my broody silkie Miss Ohio setting on 5 eggs. If they all hatch I'm in big trouble.
