My queen of the roost is very sick, I have done all the treatments I have read about on this site. She is still very sick and not moving away from a nesting box. Yesterday she got on the ramp out to the pen and threw up watery liquid. Gobs of it. I can not get her to drink or eat..She is my first hen the one on my avatar. I want to help her but do not know what else to do for her! Her comb is grey, her beak is dry, her legs are dry. I am going out to give her water but she does not want it. Any advice please.
