Scott, your flat sided eggs can be caused from a few things. perhaps one will ring a bell. bronchitis, stress, crowding, sudden increase in light. or perhaps the egg just took longer to make its way down because they are a bit old. it is more common in young pullets just starting to lay and havent got the kinks worked out yet. btw, my sons router was 80 dollars and he was told that is the most common reason for the problems you are having.
