Trama will cause swelling....... I must repeat myself again... get him on a good antibiotic... bite wounds are nasty and cause bad infections. The infection will kill him if you don't get a handle on it. If you got a dog bite, I'm sure you would get treated with a stronger antibiotic than tetracycline, same in his case. I use Baytril (from a vet) or penicillin, amoxicillin...... etc.... I don't like to use meds if I don't have to... but you are basically treating a broken leg with a band-aid. I'm not trying to sound mean, but I'm worried about him and the more time the infection has spreading, the harder it will be on him to bounce back. I would also give it to the hen with the swollen leg.
