Hello all you clever people! I've read so much on this forum about humidity, candling, embryo development, etc. And it's been exciting putting my first ever eggs into the Brinsea incubator. One thing I don't know is what day is day 21? It was a Thursday evening when I set 7 eggs, and after 14 days only 1 wasn't developing. Sunday night the eggs started to jiggle and the automatic turner stopped on Monday. I topped up the water pots, took out the turning disc, put in a rubbery shelf liner and am in lockdown with the 6 eggs which developed. Now, however I'm wondering whether the Brinsea may have been set incorrectly and should day 21 be Thursday? Lockdown Monday feels like too soon. Should 21 days mean: set eggs Thursday, likely hatch Thursday?
