I finally had a hen go broody for me, so I gave her 5 eggs. 1 broke [different story] so now there are 4. She gets off the nest at least twice a day for "too long" in my opinion (10-20 minutes), but always goes back. Today is day 14 and we candled them for the 3rd (and probably last) time today. Things look well except for 1 troubling thing...the air spaces are HUGE. For 2 of them, I'd say easily 40% of the egg space is "air" right now, with the baby chick squished up in the narrow part. The other 2 are not quite that extreme...but close. We saw movement inside, and in the 1 that broke on Day 11, the chick appeared to be in good health and developed quite well. I live in a humid environment and I figured the hen would be the man in charge in egg-sitting...so.................... Any thoughts?
