Hello and
We are glad you joined us!
Well this decision kind of depends on your environment and what you want.
If you want sweet and gentle birds you should go more for Buff Orpingtons, Light Brahmas, Buff Brahmas, Favorelles, and silkies.
If you want a hardy breed you should go more for a lot of the popular breeds like, Barred rocks, Americanas, Maroons, Welsummer, Wayndottes, Rhode Island Reds, and Jersey giants.
If you want ones for broodiness you should go more for Silkies, Buff orpingtons, I cant think of them all so youll have to look them up.
There are also a ton of other breeds you can go for too other than my suggestions, I just cant think of them all right now.
Hope this helps, do you need help with anything else?
