Just load a couple of bales of hay in he back of your pickem' up truck and
you will have cows follow you everywhere! Works even better if your wearing a cowboy hat...Ha!,Ha!
I called in a lone cow with a calf distress this year. It can definitely be done. I don’t know that I’d try it on a herd or large group, but small numbers of cows would probably be interested.
I call in lots of cows during rifle. I don’t know if it’s a distress call but a cow call brings them in like I never imagined it would. Big ones, little ones, multiple, and single.
