Thanks, we get some great blue eggs along with an olive green and chocolate colors.Not an expert by any stretch but...
1st Pic: Buff Orpington, one of my favorites
2nd Pic: Barred Rock because of the single comb
3rd Pic: Possibly Black Easter Egger? Do you get any different colored eggs?
4th Pic: The hen is probably a Black Sex-Link, the roos are likely Anconas
5th Pic: Not sure, maybe mixed breed?
You have some really beautiful birds and I love the box in the third pic!
