I have kept many many breeds over the years. I currently have 3 cochin bantams in one coop and in the second coop there are 2 black sex links, 2 buff orpingtons, 2 starlight green layers, and 2 Prairie Blue bells. It is one of my blue bells being picked on by the starlight green layers.
I have kept Brahma, Australorp, Polish, wyandotte, Easter Eggers, Salmon Faverolle, bantam japanese black tails, barred rock, partridge rock, Speckled Sussex, silkies and more.
Normally I do not sell my birds but this year adding ducks meant downsizing the chickens. Some birds fit in my flocks well while others.....well not so much.
All my birds over the years have disliked snow.
