NHR Rooster Crossing expectations & gender ID

[chicken_menagerie]

I am about to have a batch of chicks hatch this coming weekend that will be bred from a New Hampshire Red Rooster
With
Blue Orpington (looks a little chocolate) hen
Buff Splash Brahma hen
Barnevelder hen

I’m wondering what I could expect from the offspring? (Has anyone done any of these crosses). Will any of them be identifiable as male or female early on?

What will this mean the offspring might carrying genetically speaking (e.g. splits) if I want to keep track and potentially breed with the offspring one day.

Thanks for reading
