We have 5 hens, no roosters. All have been laying pretty consistently for a few months. Recently, one of the hens has been brooding, I guess. None of the eggs are fertilized so I didn't think brooding could be an issue. We noticed she had not left the nest in a couple days. She was sitting on about 5 eggs that we removed last night. When we put her out in the yard she was very agitated and went straight back to the empty nest. She is still there. Is there something we can do to break the cycle or do we just need to leave her be until the condition "passes"? We had considered locking her out of the coop, in the run, where she can get to food and water.
