Crowing
I wish there were much easier ways to find out which hen layed what without having to watch them lay every time.That is a good idea, to see if the problem is the same across all hens or if it is only specific ones.
Although the food coloring idea doesn't always work as well as it sounds. I've tried it and gotten colored eggs, but I've also tried it and gotten non-colored eggs, even though I thought I did it the same way each time. I've also had the hen wiggle at the wrong time, and get food coloring on her feathers, and then it rubbed onto several eggs in the nest (it was something like 3 eggs with the same color on them, and one was a color the hen herself could never lay.)
