I have 6 tetra tints from tractor supply that are about a week old. I found this "parent stock management guide" from the hatchery via google. It says "Commercial female chickens are showing fast feathering and male chickens slow feathering". Since this document keeps referring to "parent stock" and "commercial tetra tint", I was wondering is this the exact same breed that I would have gotten at TSC and would the sexing info be accurate. Out of the 6 chicks two have a lot more wing feathers and also some tail feathers, females?. The other 4 have only a few shorter wing feathers and no tail feathers at all yet; are these roosters are just late bloomers? Has anyone had any experience with the TSC tetra tints that can verify?
