My golden sex link was injured 10 days ago and I have had her inside in a portable cage to heal. trying to put her back into the henhouse. We have a total of 4 chickens. One of them, the more aggressive of the group keeps leaping at her so I have separated them again, but I don't have 2 coops. Does any one know of a way to get the aggressive one( petunia) to let Iris back in the group???
