The dogs defer to the Rhode Island Reds, and it is very funny to see the dogs look for, and avoid the chickens. I've seen the chickens give chase to the dogs (Miniature Australian Shepherds - good for herding humans and fur, but won't herd the feathers!). The other flock is Black Cochin. Those pretty much "get along" with everybody.
Rhodies are something else. They break all the rules for egg laying breeds, I think, because they are closer to the wild. Most brown egg layers are.
I've had heated arguments with people who swear brown eggs are inheritly more nutritious. I tell them that it is only because brown egg laying hens are more likely to be free range chickens and get a variety of food in their diet-- weeds, bugs and something other than the commercial feed fed to battery layers. Put brown egg layers in a battery with the same standard diet and lack of opportunity to exercise and you'll get the same eggs except for the color difference.
