One of my hens, either a RSL or a RIR (not sure which of the hens it is) is consistently (several days a week) laying eggs upwards of 90 grams. I feel like I could pitch it at a baseball game and no one would notice Most of these are double yolks, which doesn't bother me (its great for cookies!) but my DH is concerned that its unhealthy for this poor bird - and I can't imagine how the laying feels! Any thoughts? Is this normal? healthy?
