No need to replace. Hatching is always iffy. Still on the upside of the curve I would love the chicks. PM the cost. DH can pick them up.Beautiful chicks! But I sure hate that they were the only ones hatched. Sounds like the rest were fertile?
I have some extras, if you want to come pick up 6 more, I'll give them to you as replacements for some of the ones that didn't hatch.
