At the moment I'm selling sex-linked offspring from him, yes. I've got a blue barred girl he's covering, so the offspring will be blue, splash, or normal w/red leakage, the males will be blue, splash, or normal barred w/ even more red leakage. They'll all be rumpless and 50/50 chance of tufts. At the moment I usually sell them with combos though, like EE/Araucana/Olive Egger packages, since I only have one girl who he's over right now.
When my rumpless Sussex starts laying, she's another candidate. Should also produce sex-linked offspring, the females will be blue or black spangled orange in color.
