I've just recently separated a hen from her fostered chicks and now she is roaming the yard screaming! I know she is just calling the chicks, but it's LOUD and VERY irritating (no doubt to my neighbors as well). They are 5 weeks old now and I want to try to get them used to human contact before they get much older (not to mention she kept leading them out into the yard and the other hens were trying to kill them....seriously-one little cockerel was picked up and thrown a few times-The mama hen does NOT defend them). It has been three days now and she still is just screeching for 30 mins at a time repeatedly all day long. Is there any way I can break her of it or will she eventually just give up?
