i've been checking humidity/loss, and it's been on schedule. my hatcher is between 75-80%, so i know they're not shrink wrapping, even tho i've been openning it to pull chicks/broken eggs and check stats on the rest... most of the dorking eggs that made it to lockdown look like they quit not long after, if not just prior to lockdown. i've got one more that's internally pipped but i can still see plenty of yolk inside the shell. it also looks like a wing/leg in the air cell shadows, so wondering if the other chicks bouncing around the incubator before they made it to the brooder had anything to do with that...
again i'm thinking it was because of dirty/shipped eggs. my own bantam eggs incubated, of 11 i had 2 clears, 1 early quit and the last has pipped, so should be out soon. (8 of 8 hatched that made it to lockdown) and the EE's were hard to candle, but i've got 3 out and 2 more pipped.
I do a dry incubation and everything was on track right along. just the dorking eggs were not great... hoping my 2 girls i got start laying again. april pullets, i was told they were laying before i picked them up, but no eggs yet. they'll have been here 2 weeks monday.
depending how many eggs i get, i may start weekly or bi-weekly hatches just to see what i can get hatched from home eggs on them.
Well, they can also drown. We run our incubater at 55% +/- until day 18 when we stop turning and increase humidity to 65% +/-. Turning, temp, and humidity are the three main factors, a little but of schmutz on the shell shouldn't have been that important. Overall incubator cleanliness, which affect airs quality, is, however. 80% humidity could belabor the breath and make it difficult to muster the strength required for exclusion.
well, they were in an auto turner, incubation (dry) at about 25% humidity (weight loss at day 18 was right at 15%), i don't think incubator cleanliness was an issue, they're brand new. (cleaner than the eggs themselves) and the majority of the eggs never made it beyond day 18-19 (and had serious funk growing in them when i openned them). so i'm still waiting on the internally pipped one, and have one chick out.
she's fully fluffed now, and a bit darker than the pic shows, but here she was last night. (thinking she from the pics i've seen)
