This morning when we opened the pop door, Echo was the first to stick her head out and Delta wasn't far behind. Blue got impatient and barged through the two of them, climbing over their backs to actually get out! Everyone seemed quite happy, there were no signs of squabbling in the coop over night.
I cleaned up the coop and run in about ten minutes and as I was about to leave, Delta went up into the nest box. Being a bit stand offish, I thought it was best to leave her to it and not hover. Half an hour later, there was an egg in the box!
We noticed Echo was back in there too just as we were going out and when we got home again, another egg! Clever girls, and we feel blessed.
