My 9 month old rooster (Golden Cuckoo Maran) is sick. He has a fever - cannot stand up - and I have isolated him to our enclosed deck in a soft sided dog pop up crate that I have lined with cardboard and surgical bed pads. I have put water with oregano oil in a ceramic dish and layer feed in another. He is not eating. So I gave him blueberries - his favorite food. I have had two hens who overcame what I thought was broodiness, although it may have been an illness. I isolated them in the same manner and gave them extra nutrients. The roo however seems to have a higher temp. I know chickens run hot, 105-107, but his wattles seemed very hot when I brought him onto our deck. If avian flu or croup, they suggest heat lamp. But I am concerned that he needs cooling down. He keeps his eyes closed and when he opens at all, it is with the closed inner lid. I cleaned his nose with warm wipes. He is very lethargic. Any ideas on treating? Crop does not seem bigger than normal.
