I ordered some supposed female day old chicks from Meyer, 2 of which are my first Buff Orphingtons. Supposed same day hatch, but one has very quickly outgrown the other. Aphrodite is almost twice the size of Artemus, and has almost completely feathered out, as where Artemus is still in that "ugly" stage. I'm wondering if I may have a pair. They will be 4 weeks old Monday, so too young to sex, but was wondering if it is likely due to these facts?
