Greyish/pink comb and waddle

[Stephnrobby]

So , I just found one of my hens and her comb and waddle is pinkish/grey. I have given her a worm pill but that was just today. She does feel thin. She is not out and about, she is just resting in the coop. What could be wrong other than worms/parasites? What can I do to save her if anything?

Can you post pictures? How old is she? Is she showing any signs of molt, look everywhere for any pin feathers coming in?

Does she lay eggs? Have you seen any soft or shell-less eggs. Do you have any pictures of her? How do the others treat her? What is the name of the worm medicine?
