One of my hens is consistently layign giant 80g double yolk eggs. She is young, about 18-19 weeks, and has been laying for about 3 weeks. She is a "red sex link" or "golden comet" (I have both and can't tell the difference).
Is this bad? Can she die? What I can do to stop it?
I am feeding them Dumor grower/finisher (I have a mixed flock from 19 weeks to 16 weeks) supplemented with oyster shells.
