Hello I have 5 chicks they are about 2months and 3 weeks old and I wasn’t home but I let them roam since I don’t like them to be caged up and one of the birds I notified his wing was slightly hanging and just saw that it’s very swollen I’m suspecting a cat attack or something similar but I can’t find any bite marks or anything I applied diclofemac sodium which is an anti inflammatory cream hoping the swelling goes down not only that but the bird has avian flu so this makes me scared it might die so if anyone has any tips it would be much appreciated on how I may solve this or fix this he does not seem to be in pain or anything he’s acting normal eating grass and being with his brothers and sisters
