Sick hen

My white leghorn ( the one that hasn't laid since February) is 18 month old and going through her first big moult , she's not having a great time looks very pale in comb n wattles they are shriveled and seem to have no life in them . I have given her vitamins in her water and she's had  porridge for tea ( just nice n warm) however I'm not holding my breath on this one I'm afraid .
The other girls are all fine so is there anything else I can do or is it a trip to the vet

Cleaned out and sprayed all areas with smite on Sunday ( each Sunday coop gets a good clean) she was wormed  a while back so yes I will do this again with all . Thanks for the help.

Moulting really can take it out of them physically. Though I understand your hen hasn't laid for a while her wattle may have become paler etc as an 'outward' sign to other birds that she is not fertile at the moment because of the moulting (hens usually stop laying when moulting).

One of mine is just coming to the end of moulting. She was quiet & looked sorry for herself during the early stage and her wattles were paler in colour. She is also having her position in the pecking order challenged . She has got a nice set of new feathers though!

Hi Helen the hen in question hasn't laid in 8 months !!!!! She laid for 4 month then stopped no for no reason but as only 20 month ish I was hoping she would start again after her first big moult but well she's eating.  Drinking and running around but not much else
