hen still sick

  my girl is still unwell giving the antibiotic powder in liquid as suggested, seems to want to eat but cant. I have massaged her crop wich yesturday felt squishy, she has passed a couple of white squits from her rear, eyes still bright, comb red, very slight improvement today but noticable weight loss, what now any suggestions on how to feed her up & make her feel good again?

Have tried mealworms, noodles, lettuce, soaked layer pellets she comes to get food, not a sprightly as the other two, but once she gets there doesnt seem to be able to eat I have checked her throat she swollows fine, I am totally miffed & worried. I have read some of the other posts on this site and have seen some owners give porridge oats ?? how is it given or have I got the wrong end of the stick? thank you for your reply
