I have a beautiful partridge silkie rooster that I got a few fertile eggs from a mille d'flurre hen.  They hatched but all 3 died after a couple days.  No reason,  and others in the same brooder all lived and thrived.  So I decided to switch up my coops a little.  The same roster has now fertilized a few other hens eggs.  Different breeds of hens.  So far 4 of the eggs grew to lockdown and died before hatch.  Could it be the rooster with the problem? I thought maybe it was the combo of the milli and silkie but now it's been with an Easter egger and a cochin And the eggs didn't hatch. Others in the same incubator hatched just fine.
