Our Orpington is broody and sitting on 6 eggs - 3 of her own and 3 Marans. We have one rooster over two hens as it is so fertility is almost certain, at least for the Marans since she's more willing lol. If we let them hatch the hen will raise them on her own. Out of 6 eggs is it likely all 6 will survive into adulthood? ETA: forgive the title misspelling lol. I typed this up on mobile and it wanted to use Mority instead of Mortality. Oops!
