Hi all! I was hoping someone could take a look at this picture and give me some ideas on what would cause 3/8 chicks in my incubator to die right before hatch.. after some research I'm thinking they may have "drowned" in the egg due to the humidity being a little high. All chicks were moving around in their shells on day 18 before I put them all into lockdown. Pic of eggtopsy below:
I have a Brinsea Octogon 20 Advance - I kept the humidity around 30-40% .. is this too high? If so, what is the recommended humidity for a still air incubator like the one I have? Any and all input is appreciated! TIA!
