Ok, so my last imcubation (old rooster) i believe had between a 70-80% fertility rate.. It could have been less but definetly not more. And only ONCE ever have any of my Leghorn eggs been fertile (I have tried several times to hatch them). Now about two weeks ago I brought home an Ameraucana rooster and removed the other one. I set 36 eggs 12 of which are leghorn and tonight on day 3 I can tell very clearly that every single egg has a great looking emryo growing! That is 100% fertility, would It be safe to Assume that the Majority (especially the leghorn) of the eggs are from the new roo?
