I've figured out whats going on.
Her old owner never de-mited or de- liceed her, can only remember 1 time he put de-mite & lice spray on his chooks.
Shes over a decade old and i thought they were just old looking feet and legs, there not. She's never been treated for scaly leg mites by him.
A week ago i put liquid ivermectin on her, the print out said 0.5ml per kilo of body weight. She ways 2.2kg so i used 1ml.
Was 3 days after this she went really lethargic and not eating, she came good 2 days after that. Thought it was a coincidence her getting ill like that.
I gave her a 1/2 dose 4 days ago noticed she was lethargic and less hungry yesterday & today is just the same, nope it's the ivermectin doing it to her. She's supposed to have 1 more treatment in a weeks time but nah, im not using this on her again.
