Don't try to get past her. Call her in. Do some aggressive hen cutting. Be a young hussy trying to get the tom to notice you. When the old hen starts cussing you out,(and she will get nasty) come back to her with whatever she is saying to you. Ignore the gobbling and focus on the hen. She'll get pissed off and decide to kick your a$$. When she comes looking for you, the tom will be right behind her. Nothing a tom likes better than two hens talking dirty to one another.
