Just got these chicks yesterday at Tractor Supply. #1 was marked as a Rhode Island Red pullet, but looks nothing like what our current red hen did as a chick, so I'm curious. #2 & #3 are ISA Brown, which I've never heard of. Anyone have experience with them? #4 is a straight run Barred Rock. I'm crossing my fingers for a hen, I really don't want a rooster!
