How hot is too hot

[AMaggio]

Hi all, first time hatching eggs, we're doing it naturally under some hens. They're just now starting to hatch but the heat index is in the 106 with humidity and we're worried it's too hot. They have food and cold water but im debating bringing them in so i thought I'd reach out and ask. How hot is too hot for chickies?

Do not bring them in until the hatch is complete. A hen's body warms the eggs to the right temperature. Her body also insulates them from getting too hot. I put a fan on my broodies-hens and a turkey. The fan is not aimed directly at them but it does keep the air circulating so the temperature isn't as bad. Disturbing her now could be devastating.
