Quote: Donna you must have some hardy BR!! THough the OE and Cm  had great hatching rates also!!
My best hatches come from the BCM BR and NH.... almost always 100%.  Olive Eggers are tougher (I can't see in them AT ALL for some reason I can just tell it is dark) and the cuckoos are harder not sure why.  Ameraucans are the HARDEST!  I have rearranged pens and will be supplementing with Vitamins in the water and in about a month or so I will start hatching them again.  MAYBE I will have some new layers too 
  I have several splits about to come of age and a couple of Lavenders too.
