The black one in the back is the only one that looks *sort of* like an Orp to me.. but it could just be the angle or their age.. or the fact that i'm no expert in chickens!!
ETA: I misread your post.. either way, the Blue/Lav really doesn't look like an Orp.. fluffy cheeks and a flat tail.. me says no. The Brown/Black Roo could potentially be, but something about the shake of his beak makes me think otherwise.
Came on here to post that I deloused almost all of my girls today after finding 1 Buffie with a semi-heavy infestation last night. I think I caught it early on, as I was only able to find lice on 3 of 5 , and 2 of those took quite a lot of searching to find just a few bugs. I was only able to get 5 of 6 chickens done myself, so I will need hubby's help to get the last one (our phsycotic Jersey Giant), and will do the coop at the same time.
