I had 11 of 12 eggs last week showing live embryos when i candled eggs. Last night i candled and only saw 2 or 3 moving around the others looked like they've stopped growing in the shell. My humidity has stayed between 40 and 50% temp has stayed 99 to 101. I was adding water to bump up the humidity a few times but other than that they havent been messed with.Any ideas where i might have went wrong? April 15th will be day 28.
