I can't get a straight answer via an internet search but just looking at the 3 Basque chicks I recently hatched it seems to me that they are auto sexing. Take a look. I have two chicks that are similar in appearance with dark wings and an obvious "spot" on their head (meaning their heads are predominately dark with a light spot in the middle.) The third chick has light wings and its whole head is light feathered. Hmm?! Any one know if this is an Auto-Sexing breed?
* In this picture it is the bird in the middle that's different.

*In this picture the two top birds are the same, the bottom bird is different.
