We've spent 12 years raising chickens, so many breeds, and we've finally settled on an all-around bird. We like the White Orpington and White Rock, as they lay nice brown eggs every day, and they are easy to dress, not leaving all the ugly dark spots that red, brown, and black birds leave where the feather has been pulled out. They get pretty fat, also. In fact, we caught two Blue Andalusian hens the other night to put in with the BA roo. Then we caught the White Rock and White Orp to put in with the White rock roo, and holy COW, I was stunned at how heavy they were. They don't LOOK like they're that heavy. They have not flown the un-roofed coop, by the way, but the BA's have, since they weigh around 3 ounces.
The most disappointed we've been was with a RIR roo. Just a mess to clean. We finally peeled the skin off, it was so ugly and impossible to clean. And the RIR hen laid a little sooner than the White rock and orp, but the eggs are the same size and the easy cleaning is WAY worth waiting another week or two for eggs.
