I have a trio of bantam cochins, my roo is black and my hens are lavenders. So far every chick that I and people I have sold to have hatched seem to be lavenders. I'm not complaining but I was under the impression it would be a 50/50 hatch?? Am I thinkin in the right direction or totally confused??

If he is straight black, you should get all black chicks (carrying the recessive lav gene). If he is split black/lav, then you should get about 50/50. The odds of 100% lav from a black over lav is pretty slim.

Are you sure he's black and they're lavender?

Yep, it looks like you are right on the colors. The roo has to be split for lavender. It would be really unusual to get all lavender offspring, but it certainly is possible to go awhile with all lav. Eventually, you should get some black and the percentages will average out over time. Unusual, but not impossible.

I've sent a few batches out here recently that haven't hatched yet I'm curious to see what percentage they get. I've only set 4 eggs and one didnt develop and the others were lavneders. Not sure how many the others had to hatch but they said they were all lavenders as well. I'm sure the lil black sheep will turn up sooner or later. Thanks for ya'lls help, glad to know I'm not looseing it.

You might want to open the unhatched ones to confirm what color they are. That will also help you determine the percentage of each color accurately. I agree in small volumes, it is possible. But it should even out over time.
