I puy my broody in a cage by herself for 4 days now she was acting normal and when I left her she run for the nesting box and started acting up again. Does this mean she will need to stay in a wire bottom cage for another 4 days or so?
It seems that she will have to spend some more time in the broody buster, but maybe not another 4 days. Try letting her out again after 2 more days. Set out some treats for the whole flock when you do, make it a welcome home party. Maybe she'll get busy with her buds, eating & scratching & talking with her friends and forget about going back to the nest box. Some hens are just more determined to brood than others, and take longer to break. If she continues to go broody again & again, & you don't want to let her set, perhaps you should re-home her with someone who does want a broody hen. You'll both have less frustrations in life.
