Incubation update - I tend not to candle often - just once at about 10 days and maybe at lockdown. So, from memory at day 10..
"Eating eggs" gifted from friend 22/24 developing
Purebred eggs for same friend about 34/ 60 alive. Most did not develop. Of these about 8 were blood rings or large eggs with cracks that had died (didn't candle before setting).
Shipped badly scrambled eggs only 2/24 developing.
Store bought "pasture raised" eggs 0/24 - oh well it was a long shot.
So basically about 58 eggs made it to day 10: 22 mutt, and 38 pure breed.
I have been doing pretty dry hatches for the last year or so - add water just twice (day 7 and day 14) before lockdown. Humidity runs about and 32% without water (basement in costal San Diego). At lock down humidity is about 60% with water added.
The DIS chicks always used to look too wet, and this dry incubation greatly reduced the DIS rate.
I also try to plan hatches for when at work to reduce "incidence" of bator opening. This usually results in excellent hatch rates, and I rarely "assist".
