Always remember
Cull Hard.
Any red, cull.
Clean faced, cull.
Muffs / Beards are dominant, one copy of the gene will produce muffs / beards. Two copies will produce fuller beards. If you breed two birds, both having only one copy of the gene, approx 25% will be clean faced. I would eliminate the issue as soon as possible to avoid dealing with it later down the road.
BTW, cull is only meant to refer to eliminating them from the breeding pens. They are fine yard art.
