I am on day 7. I just pulled my last clear. I have 6 eggs these ones minus the blue I have a tan in its place. the blue was clear, but it was very hard to see in, I think it had a thick shell.
I would agree on going incubator this time of year. I hatched out some chicks in Nov. Nov. was the coldest it has been so far this year. I had 4 under the hen, but when she left the nest to eat I almost lost one that had zipped. I incubated the rest and got my 16/17 rate.
