She's 20 months old and only starting laying a few weeks ago.  She stopped laying about 10 days ago.  She has had watery poo with green in it but not today.  She's thin and eating very little but I have been hand feeding her the so called recovery diet (egg yolk, oats, yoghurt, grated apple) but yesterday and today I am hand feeding her anything I think she might eat: weetabix and water, bread soaked in milk, finely chopped ham...  I have added apple cider vinegar to her water and treated her for worms.  I thought it might be coccidiosis but absolutely no blood in her poo and no hunching or sitting fluffed up.  She's walking around like normal.  I have coxoid coming tomorrow and wonder if I should give it to her?  I have her separated from my other hens.  She's not right and is very thin and not eating normally.  What else should I try?
