Well, no matter how I massage the numbers, I don't get to try to talk sc into coming out of parade retirement... Ravyn sent me 20 eggs. I gave 9 to Frieda and 11 to the
Brinsea. At the first candling (day 7 for the
Brinsea and day 10 for Frieda--that being the only candling while they were under her) There were a combined 3 clears, though I left them all at that point.
Day 18, Frieda had all hers 'cause I like my hands not to hurt... Locked down 6 in the
Brinsea. On the borderline between Days 19 and 20, a BCM hatched. Day 21, 1 Sulmtaler. Later in Day 21, another. So 3 hatched of 6 locked down in the
Brinsea.
Frieda probably would've done better, but weather intervened. I'd forgotten that there's a leak above the nestbox she'd laid claim to, and there was a storm Sunday night (middle of Day 21). Everything got soaked, and sitting on cold, wet, wet eggs in a cold nest made Frieda unbroody (my theory as to why she quit, at any rate). I brought them in the house and, when they'd warmed up to room temp and I had a chance to candle them, I put the 6 best looking eggs in (some had drawn down before they got cold...). Had I thought to candle the eggs that were already in the incubator, I would've had room for 1 more, but oh, well. I candled again last night--except for the seeping egg. I eliminated 1 of the whole-time-in-the-incubator eggs and 4 of Frieda's eggs, leaving me 2 of each. One of Frieda's eggs hatched tonight, and I'll be taking it out to the heating pad brooder in the morning. If there aren't any pips by then (and I don't think there will be) I'm turning the incubator off.

So, from set, 4 out of 20. From lockdown, 3 of 6. From Frieda, 1 of 9. If you count last night as a mini-lockdown of Frieda's eggs, 1 of 2. If you want to count everything that's been in the incubator from Day 18 and mini-lockdown, that'd be 4 of 8. No matter how you do it, 50% is the absolute best, with cheating.
