I just picked up 3 all brown ones like your #1 and they were labled Partridge Rocks. None of the ones in the bin had any markings like #3. But they were also selling Gold and Silver Laced Wyandottes (I just had to get some of those too lol). So maybe that is what #3 is. Do 2, 3 and 4 all have flat combs and #1 have a straight comb?
Or wait, I think I am confused. Which bin did you pick each from? Is #1 a standard from the pullet bin and the other 3 are from the straight run bantam bin? Or are all 4 standards?
