Hello. I have recently been given two mature hens - one is laying but the other is not and she has a pink floppy comb. She looks healthy in every other way. However, she does visit the nesting box quite frequently but never lays an egg. Does a pale comb indicate poor health generally or is it indicative of specific diseases? Or does it just mean she is not laying. She also had very messy knicker feathers when I got her but that seems to have cleared up. Grateful for any advice - thank you.
