I think you somehow ended up with a Light Brahma Bantam without leg feathering. I've seen a Hoover's Brahma without leg feathering on here before. Pretty disappointing that hatcheries are selling them without a characteristic breed trait :/
1-Black Cochin Bantam
2- I need comb pictures and leg pictures. Are there any feather stubs? Its variety is columbian. I think it is a Light Brahma Bantam with very low leg feathering. I would also wonder if it's a Columbian Wyandotte Bantam which are quite uncommon but are carried by Cackle...
