You know, Rando, you're absolutely right. They are not required to have knowledge, say working for
Tractor Supply, but wow, if they'd just have the guts to say, "You know, I dont know the answer to that, I'm not a vet/dont raise chickens", then so many here wouldnt be throwing Terramycin at their birds for a sneeze or two. The worst misinformation is dispensed at feedstores than anywhere else I've been.
I was told when I asked one feedstore guy, who I know has raised chickens, to get me some of a particular layer feed (not their usual brand, they are a Purina dealer, but got a brand the co-op sells cheaper than Purina because so many asked for it), that it made chickens aggressive and that's what the locals want, for reasons you can imagine. Dang stuff is good quality 16% layer pellets that contains good quality animal protein, unlike Purina.
So, breeds are not what anyone should ever ask feedstore personnel about. Had a discussion with that same feedstore, different employee, about the chicks they had from Privett. The tag said "Domineckers". The chicks were all Barred Rocks, all of them, all single combed. She wouldn't believe me, who has raised them for years, even when I suggested that they were simply mislabeled, a plausible explanation. She said FFA guy came in to check on them and he never said anything. Even when I pulled Storey's Guide to Chicken breeds off the shelf and showed her the difference in the book, she refused to believe me, asked if the comb type changed as they grew.
Sorry, Patches, for the detour here!
