Broody hens will sometimes wander around for up to an hour. Most go back as soon as they have eaten, drunk and pooped. The eggs will be fine for that long.
thanks for advice its day 7 today. came down this morring opened coop and one of the hens has put 2 of the eggs out of the nest dont now if she has done rolled them out or they have fell out while she has been moving around i put one back but was very cold other one was cracked and smelled bad do hens no if the eggs are bad
