Please help. I'm so upset! My hen has been sitting on 5 eggs for 5 days. Now the eggs are gone. She is in a coop and NOT free range. I had the top of the nesting box wedged tightly so it couldn't be opened. All of other chickens go up at night too. I only have 2 roosters. I young Silkie that don't know what's going on and a grown Silkie rooster. There aren't any eggshells or signs of eggs at all. The hen is very upset this morning and was sitting on a golf ball. What to do? How will I figure this out. I did remove the golf ball so maybe she would quit setting. It's so hot here and I really don't want her to set for no reason.
