Had the 3 ex batts for 2 months now, all seemed fine until few days ago when Bo took to staying in the nest unless encouraged to come out, she is eating and drinking but nowhere near as much as the other 2. All been wormed couple of weeks back with flubenvet, and she is not showing any other symptoms, although yesterday I did bathe, dust and massage her legs with vaseline, cause I covinced myself her knees looked lumpy, needless to say after the attention scales looked perfect and the Bo kinda enjoyed it or at least didn't make too much fuss. The only other thing is that she is the last to start feathering up and has loads of new quills, could this be taking it out of her, is it uncomfortable for them? Any help appreciated

Could she be broody?

Don't think so, actually came out on her own today but still appears out of sorts, just standing round with eyes closed, has the odd moment when she perks up but doesn't last long, getting quite worried about her now

Have you checked her for signs of lice and her and the housing for signs of m redmite?
