Hi I have a breed that has black pigment in the mouth also a blue tongue.
My old red boy of 8 years 6 months is losing the black pigment in his flews they
are turning pink. I wondered if any one can suggest anything I can give him
that would help return them to black.apart from that he is well on himself.

Kelp is good for pigment, so I have heard?

I always use Dorwest Elderberry & Nettle Extract and add spinach to their feed.

Thank you for your replys
I will certainly try what you have suggested

Nettle leaf juice is great for increase in pigment, cut leaves from the plant, boil them up in a pan, strain off the leaves and poor liquid over food
