Air sac determines sex.

I candled the eggs due May 8th and none of the eggs from my flock were fertile except for one BLRW egg that has a blood ring. I’ll candle it one more time in 2 days for the May 10th eggs before tossing.

There’s prob not a correlation between temperature and air cell based on yesterday’s findings and there’s only possibly a silkie or two that’s laying fertile eggs left so I won’t bother with gathering that data.

I made another brace for the polish chick.

The polish chick’s brace came off its foot while being attached to its feathers. I don’t really see an improvement so not going to apply it anymore. I’ll put braces on chicks w toe issues soon after hatch next time.

Not gonna bother with wing pics of the silkies, they just look the same to me.

I have a baby to take care so it’s amazing I’m doing any of this at all.
He’s sleeping on my lap so posting this before he wakes.

Polish and polish cross chicks are a week old today!

I’ve been cleaning their brooder daily but they’re still messy. They’re going to join the silkies in the basement when the 14 eggs hatch April 29 or 30. Tomorrow is lockdown. Going to play musical chairs with the eggs…they go from 12 egg incubator to 42 egg incubator so I can use trays. The 29 eggs that are in there I’ll remove the Turner from the 25 egg incubator, candle those eggs again (I think 6 were removed today) then squish them all in there and the 12 egg incubator.

The only egg from the May hatch that was fertilized by the buff polish cockerel that died March 25 was by the hen youngest and least related to him, the BLRW. That egg was laid April 11. I also had a nearly developed campine cross egg that was laid March 31 that I removed today. There are a few that were laid March 30. So far the oldest viable egg is from the oldest hen unrelated to him, the Colombian rock. Her egg was laid April 8. So he was able to fertilize eggs 20 days after his death but fertilize a viable egg 17 days after his death assuming it hatches in 3 days.

It’s looking like the opposite, centered is female, sides are male? Is Mrs. Noda Fry laughing up there..about 27 days and 104 years late for an April Fools joke, Madam!

I can only go in my own experience of hatching. I do not recall ever seeing an evenly distributed air sac on a developing egg. Last year we hatched 21 eggs of them 8 were male and the rest were female.

Thanks. 8 out of 21 isn’t too bad a ratio.

As for shape index done without a caliper the campine cross came from the roundest egg at SI 77, EE cross SI 72, GLP larger one 70, smaller 68, light polish 72.
