I can't say enough about curtains. Though, I still will see a line of chickens waiting outside the curtain for a chicken to leave the nesting box, no matter that there are 5 other boxes to choose from. Also, I have had 2 chickens nesting in the same box together at the same time! They all seem to favor the same nesting box, especially if there is an egg there already. I have 9 chickens and six curtained nesting boxes. Only 2 ever get used.
And when I had a hen go broody, she would roll the eggs from the nesting box where they were laid and claim them for her own!
