I have a 1 year old Wyandotte that has gone broody. I have her separated from the rest of the flock. She is in a wired cage that is 6 foot high and 10 x 20 feet, with food, water and lots of snacks. Is that too large of an area for containment? My other option is a large dog kennel. Also how do I know when she can be let back with the rest of the flock? Thank you for your help.
