Still air , Hovabator. I have read that Dave Holderreads book says he increase temp to 102 2nd week (I believe without rechecking book,) then 103 third week ,then brings it down at around hatch time).....He says still air need to be higher than those with a fan.... Yesterday at 104 I cooled than brought it down, got to 99 and then thought I just turned it a bit to get back up to 100-101... but it was also warmer in day then night ,even though it is in the house, and I have 2 brooders lights in room with new Holderread babies, so when I open the door it was several degrees warmer in there.
I cooled them down right away, but had to go to Mothers day stuff, so it was 97 when I got back (like 5 hours later) (only had about an hour to adjust it and guessed too cool
> now I am trying to get it back.
Today is Day 19....and I was having difficulty candeling some of the eggs... wasn't sure about half of them. I set 42 from 3 ducks, but wasn't not sure of fertility of one of my ganders......And I saving eggs for up to two weeks, keep them cool in crawlspace in a bag/in a box like in DH book, and started turning the week old ones. But I had 3 infertile at 7 days I was sure of. And 6 at 12 days. I saw movement in a few, and some I just can't see into.
There are several things I wouldn't do again. Like I cooled 15 min. the first week, but then I got DH book and he says only 4-6 the second week , 6-8 the third, and not at all the first week.....
Also I should have optimized the nutrition, but only had them on layer pellets with some greens and oyster shell.....
Well, I guess if any survive, I need to keep them for breeding as they are one tough duckling.....
