Hi all, my 4 girls should be laying in the next few weeks and are starting to act funny. They sleep either in the next boxes or on the rim of them, and they prefer to poop in the boxes, leaving me with a little mess to stir around or scoop out. Will they lay in the boxes after using it as a dump area? Also, i am reading that people put in golf balls to encourage laying. Any idea how much time that takes hens to get the picture and lay after balls are put in? Do you put 1 or 2 in each box? Also is oyster shell mandatory for laying or do they get enough of this from pecking at the ground? Thanks, Jen The gal who posted in the summer about fears about zoning bothering us...still have the 4 hens!
