Hi Twinkle, My Boulder has stopped roosting for the moment, they usually do when the temperatures are like they are. But they do seem very tolerant to our activities so I wouldnt be too worried, I remember Matt had a whole patio laid near to his BT nest and all as ok.
Been a flurry of activity the last few mornings, lots of Blue tits, Great tits checking out the boxes. No roosters as yet but lovely to see all the activity. A good variety of birds too next season is coming fast
