I had a chick hatch this morning at only 16 days. My Buff Orpington went broody so I went and got 4 fertile eggs from a friend. I clearly marked the 4 with, 6/9/16. Then on 6/13/16 my friend gave me another Americana egg to add to the bunch. I marked it before bringing it home. I added 2 more Americana eggs on 6/14/16. This morning I checked on Mama and heard a peep. Lifted her front up to see a wet new baby born. Egg shell was marked, 6/13. I was concerned. Waited a couple hours and checked to see a perfectly healthy baby. Isn't this really early? None of the others have hatched which is fine since they weren't due to hatch till tomorrow. OH...and this first time chick hatching is soooo exciting! I don't know who's more nervous, me or Buttercup!
