So glad to hear they are healing. How much younger/smaller is the chick than the rest of your flock? They really should be close in size before you put them together.
It might be better to fence off a small section of the run for your younger two, so the others can get used to them for a couple of weeks without being able to attack. BluKote on the scab will deter picking of the wound. At night, maybe they can stay in the garage. They could also stay in the coop at night (chickens have extremely poor night vision), but you would have to put them on the roost after dark and get out there before sunrise to put them in their pen. If you lock the two in the coop, and the others out, you will still have introduction problems when the time comes to put them together.
When they are big enough to be put together, here are some things to consider.
Do your chickens ever get time to free range? Often it's best to introduce in neutral territory.
I introduced 2 younger pullets to my flock of 9 hens and thought the most dominant hen, if any, would be the trouble maker. She was her usually bossy self, but it was the couple of girls lowest in the pecking order who really gave the new girls a bad time. It seems they finally had someone to pick on and were not going to waste the opportunity. There was plenty of space in the fenced yard so the new girls could get away from the meanies, but it took a month before I put them in the coop & run. (They stayed in the garage at night.)
Sometimes you can change the run around to distract the chickens. Add some branches or build a simple 'jungle gym' they can go on and under, some roosts or even a swing. Put in an extra food bowl and water dish. They will be highly suspicious of any change and pay less attention to the new chicken.
See if there is one or two hens that are causing the most aggression and pen them for a week or two. The flock dynamic will change and when the meanies are reintroduced, the new chicken will already be part of an established flock. Squabbles are normal, but continued aggression can become a problem if they pull feathers or draw blood. You've really got to watch and observe what is going on.
By the way, what are your plans for the turkey? Won't it be too big for the coop some day? (I've never had a turkey.)
