Will high humidity effect a broody hen hatching eggs

[Alex saeed]

Can a broody hen hatch eggs when outdoor humidty is 70 to 80 percent

My hen is broody and despite my efforts is unwilling to break broodiness. It is rainy season and humidity is quite high in range of 70 to 80 percent. I have placed 19 eggs under her as she was not breaking broodiness but i am not sure whether the high humidty in air will effect the hatching under broody hen or not?

Do it all summer long around here. Pretty common to be 70-75%+

Ive never experienced any issues with eggs hatching under broodies when humidity is very high due to frequent rains. Only problems have been when summer weather was very hot and dry, and ocassionally chicks became shrink-wrapped.

Having 19 eggs to keep properly warmed and turned may be a bigger issue re hatchability. I would candle the eggs after your broody has been incubating them for several days, and toss any that dont show veining. That will allow her to better tend to the viable developing eggs. Depending on the egg shell color, the embryo and veining will be visible under a bright light in as little as 4-5 days. (Darker egg shell colors such as olive green and dark brown are much more difficult to see through in the early days). Good luck on your hatch!

Broody birds have the ability to add or subtract humidity from the eggs through their skin. Pretty amazing.

high temperatures and high humidity due to rains, two of my eggs hatched on day 16 . Further two hatched on day 17.
Today is day 18. No more hatches yet.
One of the day 17 egg did hatched but it was dead when i checked. This egg caused alot of filth on other eggs and also small ants cam all over it.

When i noticed i removed all 12 remaining eggs and placed them in incubator. It is now day 18. From the morning the hen is wandering with 3 chicks. Is there any chance of more hatches as the chick that was dead caused alot of filth and made the nesting area under eggs damp . Can eggs over that damp area still hatch?

I placed 19 eggs total at 10.pm on 5th of july . So today is day 18 . 2 eggs hatched on day 16 i.e. 21 july and 2 more on 22 july. But no more hatches in last 36 hours. May be the dampness has effected them as no cracks visible either.

Out of 19 . I removed 3 on day 10 after noticing no development during candling. Out of 16, one is dead , 3 are healthy and with the mama hen. 12 eggs i have placed in incubator since yesterday.
Should i do a water test to check any signs of life???

Don't, as you might just drown them and what they need most at this stage of incubation is oxygen.

Did you put all eggs under the broody at the same time?
Were the eggs different in size and age? Meaning small and big eggs, fresh and/or already up to 10 days old?

This would explain the early hatchlings.

Yes all eggs were put under broody on 5th of july 10.pm.
Regarding size yes there were variation in sizes.
About being fresh and old. They were mix. Some were old like a week or so and some were fresher than them hardly 2,3 days old
