Hi! I have a blue andalusian hen that is just over a year old. This morning I found her dead, she has been looking sick for a few weeks...her comb was either a pale red, red or had some purple in it, her feathers weren't as soft as they used to be they are pretty course and a little broken up and her coat had lost some color, her feet look ok, she recently has had a change in behavior. We know at least one of our hens had visible signs of roundworms, we wormed them with wazine and 12 days later treated them with Ivomec Eprinex. She was avian flu tested. Please, Please, Please if you have any suggestions let me know!!! Do I need to worry about my other chickens??? Thanks!!!
