I think it would be interesting to hatch out more of these horses and study the feathering out patterns.Their wings are so different.View attachment 1720173 View attachment 1720174 View attachment 1720175 View attachment 1720177
My bantam cochins noticeably feather out differently depending on sex. The males have short little wing feathers and take forever to feather out on their backs. The females feather out evenly and have longer wing feathers.
It'd be cool to see if there was a way to tell with your horses.
