My 1 year old hens have all of a sudden started eating their eggs. What can I do to stop this? It seems like as soon as I open the coop to collect the eggs, the hens run for the nesting boxes and start pecking at/eating the eggs. Some have already been eaten by the evidence left in the boxes. I'm at work all day, so I can't collect the eggs earlier in the day. I did try putting a few golf balls in each box, but it doesn't seem to be helping. ... Help!
