I have a new layer as of yesterday, an Easter Egger. Today I went and gathered eggs and noticed her egg had some blood on it. Is this normal? Will she be ok? Does she need the vet? I have a silkie brooding some eggs that were fertilized. The 21 day mark passed yesterday. How long do I go before assuming the eggs are duds and disposing of them?? She sits in them religiously getting up to eat and drink only. Poor baby girl.
