Our favorite seems very sickly

[SHH]

We have a lavender orpington about 18 months that has just gone through a molt. She is very lethargic...seems to sleep a lot...and most concerning of all her comb is very pale and droopy. However her appetite is ok...she is still laying...and if anything is more aggressive than ever to the other girls...especially when it comes to food. Suggestions please?

What's her diet?
Have you checked for mites, lice or de wormed them?

Diet is currently 20% protein crumbles supplemented with sunflower seeds and scratch grains...no sign of mites or parasites. Our other 3 girls seem very healthy.
