Merlin, don't forget with feral/hard strays there can be more than one father for a litter. It is possible that the positive kitten's father was positive and the father for the other kitten was negative.
Yes the kittens should be retested in 4 months in case they picked up the virus from the positive adult kitty. Personally I'd start vaccinating the negatives now. They will need a booster shot 3-4 weeks after the initial shot. You have a well thought out plan. Can your trapping partner deal with it?
