Have an ISA brown who is definitely going broody. Has been sitting in the nest box that the majority of the girls use for the last 3 days. She won't come out unless I physically move her. Even forced 2 hens to use a different box today. Today after work I went out and made her get out of the box and go outside in the run. She was all ruffled up and basically is making herself a target. She is all ruffled up and shakes her feathers out and is grouchy with the others. The others were calm until she went out in the run. She also clucks constantly. A couple others went after her, I assume because they think her behavior is odd. Any advice? Will just removing her from the nest box every day be enough to stop her from going broody? She did this one time right after they all started laying and gave up after I moved her for a few days. Seems pretty determined now. Should I put a fake egg in another box and let her sit on it? Don't really want to encourage the behavior but don't want her hassling the others who want to lay. Thank you!
