I would keep him safe until you have the Blu-Kote. Then when you reintroduce him, if she goes after him, separate her for a few days to a week. Sometimes this allows the pecking order to adjust and she comes back in at a disadvantage. I have tried this and it worked after a couple days and other times it failed, so I ended up taking the aggressor out for a couple weeks and then it worked. However, it was in a separate coop and run, not in a crate. I just think he will be fine once you have the Blu-Kote. And btw, it's medicinal as well. Usually once I have that on, I just keep an eye on the chicken and reapply as needed. Works for me, and one thing I unhappily have a fair share of experience with is aggressive chickens. All is calm now, but I have 4 littles, so we'll see. LOL Well, I have one aggressor, but she is only aggressive with me. She is actually quite adorable, but every few days I have to pick her up and carry her around for a few minutes to remind her who is boss. She growls the whole time.Unfortunately, all of my coops have different groups of chickens or guineas in them. I would end up with an even more traumatic situation for everybody if I tried to put him in a space with others. I have the same predator overload up here but my coops are in sight and easy reach of the house.
Interesting you said to separate the aggressor. Do you think the rest would leave him alone if I put her in the kennel instead? He is the injured one so I'm not sure how the other hens would react to the bloody areas, even if they have been ignoring it so far.
