Oh my gosh..I have major chicken envy. I want an orphington! Pretty girls! My son has that shirt too (in red) and if he could, he would wear it every day! Now, thinking I might need one after seeing you in yours.
sometimes an orpington with red on it is a sunrise orpington
you get these by breeding a buff orpington with a Rhode island red
i have a couple here at my place, they tend to be a little smaller than a buff.
PS: here is my 2 new lemon cuckoo roosters along with a couple of my hens
