I had 5 white plymouth rock hens and no roosters so I added 2 buff orpingtons roosters and these are very large birds. They look ike a tan buff orpington. Will these work better for the cornish crosses then? I see cornish rocks in the freezer section aat walmart so i thought this is how you get them. I don't know how to add pics on here or i'd add them. These birds are laying big beautiful brown eggs even from the start they were bigger than the others. I've got about 10 hens of the orpington rock X's. I been waiting 4 months so far to put my cornish roos to good use and I'll be selling the other 10 or so off very shortly. I've just had the quail to raised and butcher until now. I guess I kinda screwed up. I've got 15 dark cornish roosters and 15 dark cornish hens I was going to keep raising them as I thought I had to have them for the cornish X's
