We have a mix.
I don't know the breeds. I think most of them are mixes. Most days half of our eggs are a tan/brown color, and half of the eggs are varying shades of green. None truly blue. None white. We're interested in eggs and meat, but mostly just for the experience. We're not interested in showing.
All 15 of ours seem to get along well, but we've got our eye on two, and think they are young roosters. These two are Patches and Rusty. Too bad because they're such pretty birds! I don't think we'll ever see eggs from these two...
We have three Buff Orpington (These two are Lola and Loosy, Lilly wasn't participating - she's lighter in color than these two), or at least a BO mix:
Then we've got our three old ladies, given to us by friends who couldn't bear to eat them (we call them Dumplings, Coco Vin, and Enchilada):
Our two youngest are Char (as in charcoal) and Ash. They're not consistently laying yet, but we think one of them gave us the tiny mouse fart of a green egg.
Big Red is a loner, but not anti-social. She just doesn't seem to have to be around the others to be comfortable. We think she's a partridge colored Rock or Road Island Red.
Jon Staples is grey with black head. Lilo, Marcy, and Vi are all Easter Eggers as far as I know. Lilo does not have a beard and sideburns but looks like the other two in coloring. Marcy and Vi have beards and ear muffs (no picture of Marcy but she looks like Vi with the ear muffs but is slightly smaller). We're planning on adding some Bard Rocks. So this is our motley crew.
