How long has she been broody? When do you plan on giving her the chicks? Do you have a back up brooder in place in case she doesn't accept them or attacks them? How many chicks are you giving her and is she a full size hen or a banty? As long as you don' have too many and she accepts them she should keep them warm.My name is Kate I am getting chicks and we have a broody chicken (hairy legs) it is really cold outside like 30 will my hairy legs keep them warm all the shealter they have is a bucket which is a being used as a nest will the chicks be ok?
