Hi I am having this problem too - I am getting one a day , laid in the nest beside the broody but the other 4 have stopped entirely! Like yours mine had taken to laying under plants and in the borders but even that has stopped. I was wondering about magpies as I have some hanging around - but it seems to be a widespread phenomenon if you read other posts.
I wonder if the same is happening in battery farms? Will we be seeing eggs selling at £5 a dozen soon?
