Hey for 3 week old eggs..... That is a great hatch rate ~ especially if they were scrambled upon arrival with cracked eggs.
I just bought 10 dozen Pekin eggs, shipped & packaged great in the boxes, and one arrived completely intact
, and the other was mangled & stinky & crap
So I had to wash ALL the eggs in one of the boxes & smelled FOWL rotten
~ and the other I put in just fine ALL intact.
I currently have 76 eggs going into LD today out of the 90ish eggs that made it thru transit intact (I bought the 120 w/ 60 in each box) So the one that was mangled I knew I would not get many to hatch after losing a dozens that were cracked, & the others not cracked coated with rotten egg, and then being washed.....
So the guy refunded me total cost for one of the boxes, which was really nice of him.
