What should i do with these eggs?

It sounds like all that are going to hatch already have. I would give them to a pig or dog to eat.

 

Are you sure that all the eggs incubation started the same day? Or is it possible that other hens contributed to the nest during the last 3 weeks? Did you candle them?

You can also compost them.

 

Composting is a good idea if you have a secure composter. You have to be careful about attracting predators.

 

Yep, I would candle them first to be sure they aren't alive in there. I always like to open mine up that don't hatch to see if I can figure out why/when they died. But that's just me.
