Unfortunately most of those look a lot like my rangers, especially the ones that are getting coloration on their wing feathers. They're quite a bit yellower than my rangers on average though, too. So I'm not sure, though that could be a hatchery difference in the coloration since rangers are not exactly bred for conformation. Your tractor supply definitely needs to know this is a problem though! I mean, mine usually does "assorted reds" but they're usually assorted sex links and RIR/New Hampshire, all of which are good layers. Broilers should never be mixed with breeds like buffs!
