I'm seriously tempted to try a sebright (or similar game) crossed with Araucana - to get a bantam Easter Egger.
A pint sized crested terror that lays blue eggs - could be my style of chicken <3
I have two colours I'd like to see:
Black/Blue/Splash (Achievable from the Araucana's)
The highly melanised laced, spangled, and patterned (Achievable from the sebrights).
Edit to add: I'm not sure what the feathering would be like. You would be crossing a somewhat soft feathered Araucana (that makes crests nice and floofy) to a somewhat harder feathered Sebright. You might get mohawks rather than crests?
