we just started to get eggs. IT IS SO EXCITING! My 11 year old went out this morning in pajamas and a coat and came back with a new egg. It was -26C!! I found another one this afternoon and it was still warm and in the nesting box.So total from 10 girls thus far is 2 Saturday, 1 Monday and 2 today. This afternoon's is the first one found in the nesting box. The golf balls really do seem to work. This site is great! THanks for all the wonderful information. I am learning lots.
