Went into lockdown today (day 18), but some basics had changed. I read another treatise on weight, where it says 15-16% was ideal, not 13%. Hard to say who is right. If 16% is ideal, then today 13.7% would be ideal, and my average is 11.1%. So, again based on readings, I choose to start lockdown without changing the humidity, its still at 22%, the lowest I can get in my bator (if the house is higher, you can't get lower in the bator). I did take some other advice I read, I filled channel 1 and 2 of my bator with rolled paper towels, then put a layer of paper towels under the mesh, and another layer on top of the mesh...then laid the eggs on their side on top of that paper towel layer. The theory is, when I add moisture (which I will do when I see the first pip), I will get a lot of moist surface. Ideally, I'd have 2 bators, one for the ones that have achieved their weight loss, the other for those that haven't. You keep the ones that haven't had sufficient weight loss at low humidity, the others get lots.
Anyway, I currently have 34/41 in the bator, all that have failed failed because of being not fertile. I think this incubation is going to be 4 or 5 days long, as today's candling showed a huge range of maturity.
Only 4 more sets of 41 to do...lolz...;-]
