Mille Fleur D'Uccle X Buff Orp???

[bufforp89]

I have a D'Uccle pullet that recently started laying eggs and I noticed today when I cracked some open that they are fertile. I was wondering if it is possible for my Orp roo to have breed her? I assumed that he was way to big but he is my only rooster in that pen and I know they are her eggs because she is the only bantam on the place. There are no little roosters here or at any neighbors that could have gotten in with her. Is this possible?

Yes is it is quite possible for large BO roos to breed a dDuccle hen enough to fertilize the eggs, though I worry that the small egg may not give enought room for the chick to grow since it should be considerably larger than the d'Ducle bantams, if chicks do hatch though the should be buff, or buff colombian colored and genetically split for mottled.
