I have a hen that is at day 20 of sitting on eggs. She got off the nest today to eat and take a small drink so I looked at the eggs to see if any might be piping. When I looked at the eggs, they are dirty with some yolk on them. That was not there before. I think she ate one or 2. Will the others still hatch? I do not have an incubator to put them in so she is the I my chance they have. Any info would be appreciated.
