Kaffaarah for having intercourse with one's wife while fasting in the month of Ramadhaan

Q: I have a kaffarah for breaking a fast due to intimacy during time of fast. May allah forgive me.

Do I have to fast for 60 consecutive days or can I feed 60 individuals?

Also, if I have to fast should I do it with no delays after Ramadhaan? My issue is that I'm waiting for a doctors appointment which I have delayed already. The appointment for endoscopy will consist of taking medicine before hand and then I will go under general anesthetic. My concern is if I have to fast and I get an appointment from the doctors, I will not be able to keep the 60 consecutive fasts.

Therefore do I start and have a break for 2 days then continue?
