I wish given two pullets and a cockerel. They're about 13 weeks old, but are very small. If they were eaten, they would be smaller than a small cornish game hen, I think. I have three sexlink roosters the same age and they're easily 2-3 times larger. My rooster is very small, but already showing downward tail feathers, but my sexlinks did not show downward feathers when they were that small. Anyone have experience with how long it takes them to reach maturity? Just wondering if the hatchery sent my friend bantams by accident.
