This morning, just like the day before yesterday, Peaches and Barley were doing a lot of shouting. I checked on them and Peaches was in the nest box with Barley watching from outside.
I grabbed my camera and was just in time to see Barley go into the nest box with Peaches.
Peaches looks a bit squashed under Barley and her egg is just peeping out from under her. I removed the egg and could see that there was no doubt it was Peaches because it was the same long shape of her previous egg.
Peaches came out of the nest box and Barley settled in. I checked back about ten minutes later and when I lifted the nest box lid Barley came out shouting and there was her egg.
So now they are even laying their eggs together. They really are a very together pair of girls.
