For several nights now, our blue-tit has been seen sitting, but only very late in the evening. But this evening was different. She went in at about 7.30 and has stayed put but is very restless. She has at least two eggs, and seems to be turning them about every five minutes. I hope everything will be OK as it is due to be even colder tonight.
As they lay one egg a day, we were probably mistaken in thinking that she was laying back on 11th April. However it's all very exciting!
