porcelian belgian d'uccle

if I crossed a mille fleur to a porcelain will all the chicks be split to porcelain? Also how long does it take for a duccle bantam to fertilize a hen,basically how many seconds does a roo have to be on a hen in order for her to start laying eggs.

Hello community! I have 3 little porcelian D'uccle babies, 5 weeks old, that I think are boys. I have labelled them 1. 2. and 3. In photos. What are your thoughts? Am I right?
