Any ideas where these wounds are coming from? Do you have any antibiotics human left over from a vet? Do the Epsom salt compresses then treat these places with some kind of wound spray or antibiotic salve. To give oral meds I wrap in a towel like a burrito that way they can't fight and it's easier also having someone to hold like in the picture can help too then you have 2 hands free. Do you have meal worms? before starting the b complex toss some out so they get a taste for them. Meal worms are like crack to poultry once they get a taste for them they will gobble them up. You can try the b complex that way.
