I dont know if it is definately gapeowrm but i am desperate for help as my hen seems to be dying. She started with the flicking head, gasping and squeeking like broken dog toy. i gave her and other two hens flubenvet but she has not improved. To be honest i dont think she was eating the food to get the flubenvet. She has become very letharging and we have been syringing diarolite into her to give her some goodness and have put her favourite food under her nose with the flubenvet powder on, but she is refusing that too and now she can hardly stand up from lack of nourishment. i have now brought her in the house to keep an eye on her and to stop the others picking on her as she is weak. Can anyone advise how to treat her if she is refusing food? Can i dilute flubenvet in water and syringe that down? if so what is the ratio? I am new to this website and would be ever so grateful of advice to save our hen. Thanks in advance.
