Ok, so I know that the temperature is a bit low, my incubator is stuffed, and needs to go back under warranty, but I continued none the less. Last night was day 17, so I cancelled the eggs prior to lockdown, but I'm sure development is well behind, I could see darkness, but only in about 1/4 of the shell. Couldn't see any blood rings but couldn't see any movement either (although didn't look for long on any eggs). Has anyone else had this at day 17 with any successes? Should I go into lockdown regardless or wait a bit longer?
