What is this?? 6-7-2024 at Rural King I bought 5 melanistic mutant pheasant chicks (along with 3 Cream Legbar, 1 Barnevelder, 1 Salmon Favorelle, and 2 turkeys – all are now still in my brooder coop together). There were about 45 pheasant chicks in the tub. All pheasants looked same size (smaller than chicken pullets) and very similar to each other; but a few had slightly more light splotches. I picked one with more light splotches. Over 10 days it gained more light feathers and is clearly not like the other 4. Pics are 6-29-24, 3 weeks after purchase. Chick is significantly different color than 4 pheasants, and larger. But sticks with the 4 pheasants, and (like the 4 pheasants) is more flighty than the pullets or turkeys. Any ideas?
