Though you can say that a breed is friendly, it depends on the individual birds. This is the same as choosing broody breeds. Like humans- they all have their personalities and their way of acting toward an instinct.
My best of luck with broody hens has been all over the place. I had two Australorp hens- one being so motherly and the complete opposite. You can never assume when involved with nature's creatures.
1). Salmon Faverolles
Each of my Salmon Faverolles have been broody more than once... I've never had them hatch, but they are very protective of their nest and are such sweet birds.
2). Blue Cochins
I've only had Blue Cochins, though I know many other Cochin varieties will/may go broody quite often. The Blue Cochins of mine are very motherly... often going broody not long after their first hatch. The only issue I've had is that they are more prone to breaking eggs accidentally when positioning in the nest.
3). Buff Orpingtons
Can be very persistent, independent birds. Will probably make a very good mother. My one hen tried very hard to hatch, but our rooster, at the time, was infertile.
4). Sussex
More eager of birds- will go broody- not extremely motherly.
5). Brahma
More on the tough side... I love this breed, they are my favorite, but mine tend to go stir crazy when separated with chicks too long. Other hens will do this also, but the Brahmas like a little more freedom.
Best of luck and God bless. Hope this was helpful to you.
