I have a broody silkie, and this is our first broody. She has been sitting on the eggs for 11 days now. I orignally put 8 eggs under her. Twice now, I have found one of the eggs busted and nothing left but part of the shell. The first time I had not yet isolated her, so I assumed one of the other birds had messed with her nest. No big deal. We have since isolated her. This morning I let her out for her morning poop. I noticed one of the eggs was missing except for a few pieces of shell. My question is this: the remaining eggs are sticky now; will this hurt the remaining eggs? What shoud I do? Thanks.
