Random, bizarre question! A couple of my chickens just started laying today, but they laid in the chicken run. I got 3 golf balls from a friend to put into the nesting boxes to help the chickens lay there instead, but 2 of the golf balls are neon yellow. Does the yellow color matter to the chickens or should I paint them white? (Would use non-toxic paint if so.) I just want to help them out as much as possible so they will lay in the nesting boxes.
