Hi Dick,
A capped egg is when the babies start to hatch the half egg shell may flip over on top of another unhatched egg, therefore capping that unhatched egg. When you do nest checks, look for these capped eggs and if you find one, carefully remove the half spent eggs shell from the unhatched egg. Hope this cleared things up.
Mite control, heat venting, predator protection and additional feeding during bad weather add up to success.
