I use shavings/straw in my nest boxes and my ladies know where to go lol! If I find one somewhere else I lock my chickens up to find out the misbehaving one..I hate playing hide and seek cause my chickens are all free range. Golf Balls or fake eggs in the nests really do help...just leave the eggs untouched (the ones in the nest boxes) and pick up the other eggs and put them in the nest boxes..it will help promote good behaviour !
