Thanks when you cross breed two different breeds what does the chick get from the male and what does it get from the female like if you breed a millie fluer d'uccle rooster with a blue cochin hen what color would the chick be and would the chick features look like the nillie fluer or cochin I'm asking because i saw a post @ breeding and it said you get the color and breed from the female but this post was about how to breed a frizzle and that the frizzle comes from the male
None of those things are true. Frizzle is a gene that can be from either parent. It's better coming from the father because you only need one frizzle rooster and many regular hens to create frizzle chicks. However, you can have many frizzle girls and a regular rooster and get frizzled babies.
As for the question above. It won't have markings like the mille fleur. I am pretty sure it will be a plain colour. Can't say for sure though.
I have never seen the cross before. You most likely will get a full feathered bird with feathered feet, beard/muffs and a single comb. I may be a bit bigger than a D'Uccle in terms of width.
Google images didn't help me locate an actual reference picture, so I'm sorry I can't show you what the possibilities are. There are a ton of silkie x d'uccle mixes - and they are stinking cute.
This is what the chicken calculator gave me for colours.
