Recently my 2 month old change ck managed to landed in hot oil, 4-5 days ago. He got is lower body burnt. I am treating him at home. He sits the whole day and can only walk for 4-5 minutes. Recently one of his legs has swollen and turned purple. Rest of the body is healing. Is this the sign of an infection or the leg has turned purple because of lesser blood circulation in that area as he keeps sitting the entire day. There is no vet over here. I don't know what to do.
