Hens Donating Eggs to My Hens Currently Sitting! Now what?!

[Blueeyez]

So, I have 2 hens that have each been sitting 7 eggs for a couple of weeks now. Well, today while one of them was taking a break, I noticed she mysteriously had 9 eggs! A couple of hours later I went back out and found another OEGB cuddled up next to her on the eggs...... I'm certain she is the one donating eggs.... So now what do I do? Because the "donated" eggs are going to be way off as far as timing goes! Not to mention that they have each started incubating on a different day

Common problem/issue. You should have marked the original eggs with a marker or some such to tell which they are from those added afterwards. Too late now but you can still mark what's there and after the hatch, the few remaining you just toss, or put in in incubator.

I write numbers 1, 2, 3... etc REALLY BIG and on both sides so that they can be seen and you will know if one is missing.
