Very nice! And all together too! Mine always scatter or run, it must be my bad timing! Lemme guess: sex links, leghorn and what's the one in the back? I'm probably totally wrong on the guess
Oops. Guess I should have said. Let's see. Bottom red is Rhode Island red, larger red is New Hampshire, the white is a Delaware (my leghorn is moulting and forbid me to take her pic) and the black is an Australorp. Good guesses though, I wouldn't know 'em if they weren't labelled when I bought them.
