I found I got approx. 1/4 chicks that looked exactly like the original cross: with moderate black feathering, black legs, and a bright red, rounded comb and wattle.
Approx. 1/4 look typical White Leghorn, with narrow, high combs, and yellow legs.
Approx. 1/2 are like the original cross, body shape and size, but with smaller comb and wattle, and white/pink legs.
Here is a photo of a hen like the 1/2:
They are great. They began laying at 3 1/2 months of age and have the same easy-to-get-along attitude as the parents.
