I keep my chickens and horses separate but that's mainly because my chickens can get into the dog area if I let them out of the run. Dog and chickens definitely don't get along, at least mine don't.
I had a rooster that hung out with them but something got him a few years ago.
A friend keeps her chickens in with the horses. Just turned a stall into a hen house for laying eggs. The rest of the time they are out scratching through the horse poo looking for fly eggs. They really help on that front. She tried some guinea's but they just peck at the manure, don't actually scratch at it and dig the fly larva out. Guinea's are better at catching live bugs.
I love Buff Orpingtons, they are very friendly calm chickens but their eggs are rather small. If you're wanting lots of large to jumbo brown eggs I suggest Production Reds. I've had the RI and they give good sized eggs but not as many as the productions. I think they are a cross between a RI red and the New Hampshire red
ETA- Just wanted to add that old plastic barrels laid on their side can make a nice hen laying spot until you get a coop built. I have a friend who uses them stacked up and bound together as his only chicken shelter inside a fenced area.
