HELP PLEASE the vet was useless I have a chicken that has been sick. I found out that she has a tapeworm. She has had an impacted crop for two weeks. Food is starting to move through her now and that is when I saw the tapeworm. I read on here that deworming them when they are sick can be fatal. She has lost a lb but is acting well sun bathing cleaning herself. She will not eat much. Should I give her the dewormer since I think it is causing the issue or will that kill her?
