I think if the feedlot wants them, they should pay you extra for getting the information, don't give it to them for free b/c they are bound to make an extra 15-40 head. Them not you unless you demand more. We are delivering in the morning and were sending the age and source tags with the trucks, until the feedlot said they didn't want those ones and wanted the records so they could put other tags in that they have some sort of alliance with. rediculous, every feedlot should accept every age and source tag and help the producers get some information back on their calves.
