Is it possible to get 6 straws in one of the plastic tubes in a cane. I keep great records during breeding but went to thaw a unit this morning and there should only be 4 straws in the bottom and there are still 5. I am worried because its a heifer I am dealing with. I have checked all use gloves and no other bulls names are on straws to suggest I grabbed the wrong straw and all other numbers in that canister are correct.
