No, you can't in 55. The cow tag you get in the draw is an A tag. The OTC bull tag is also an A tag. You can't have both.
You would need a B cow tag to go along with the A tag OTC bull tag. The B tags for a cow would be private land.
If you're going to all hunt in 55. Just all get an OTC bull tag. You can buy them all the way up to a day before the hunt starts, or even after the hunt starts at a DOW office.
