I have three buff orpington pullets (11 weeks old tomorrow). One is very tiny - about 2/3 the size of the others and about 1/2 the size of my silver laced wyandottes. Could I have gotten slipped a bantam from the hatchery? I'm a new chicken momma and have never seen a full grown bantam to make a logical comparison. She wasn't that much smaller as a day old chick, but she sure is now. The friendliest of the bunch and the first to try out anything new. She comes when called and will sit on my shoulder and roost on my arm. Very sweet indeed. She is healthy, active, eats well and her feathering is at the same stages as the others. Do I just have a tiny large fowl or a large bantam on my hands?
