You are correct, in your county during muzzleloader season you cannot take does unless by MLD Permit only.
VS the new law in Red River county.
Muzzleloader Jan. 2 - 15, 2017
Antlerless Deer General season buck limits apply, antlerless permit required only on MLD property.
In that county you can take does without special permit but if it is MLD property you need a doe permit.
