Hi ok so i have 5 (jumbo??) coturnix quail ranging from 1.5 weeks to i'd assume 2.5 weeks. They all have partially feathered chests, some more than others. Can anyone at least help me with a few? It'd be very helpful. Thanks! This above is my oldest chick, Ghost. 2.5-2 weeks old. This one is my second oldest, Nugget. leaning towards girl, but what do i know? This one's like a week and a half old.
