Hi I'm pretty new to hatching ducks and I'm worried for a few of the eggs. I have two that are internally piped (can hear one chirping) and one that over night went from white to this scary looking blotch on the bottom of the shell. Its still moving and chirping inside but it has been internally piped for about 3 maybe 4 days now and I'm worried. To make a long story short, I have a mamma who was sitting but kept pushing out all the good eggs. I rescued 3 cold ones that after bringing inside and incubating for a bit, found that they were still alive. She just gave up last night after sitting for a month and a half...(Way long) The egg she abandoned last night is the one in question. I have 5 eggs that I'm incubating and all but two are different ages. I have done a lot of reading and decided to join so I can ask for your help. I have candled the eggs and have done my best at guessing ages but again I'm new to this. Any help would be much appreciated. I have more pics of the other eggs as well as videos. What are my next steps for these ducklings?
