Ebony and Flame are so in sync with their egg laying that they both want their favourite high nest box at the same time. Ebony takes longer to lay her egg than Flame does so sometimes Flame joins Ebony in the nest box and Ebony will leave and return a few minutes later when Flame has laid.
Sometimes Ebony will reluctantly allow Flame to share. Now that they have settled into sharing a nest box they are a lot less noisy.
When I looked in the nest box yesterday Flame appeared to be virtually sat on top of Ebony. She had squeezed in behind her possibly so that Ebony couldn’t chase her out.
I went to get my camera but when I returned Flame was standing in the egg laying pose and her egg was beneath her.
As soon as Flame had laid her egg she left the nest box. About ten minutes later Ebony left the nest box and as usual their eggs were side by side.
I am so glad they have got this sorted out at last.
