[Disecky]

i have had a couple birds inside (60 deg) for a couple days.
Is it ok to put them back outside where they were? (10-35 deg)

I would slowly reintroduce them to cold. If possible outside in isolated area with heat lamps. Every few days decrease amount of time heat lamp is on. I would say in total after 3 or 4 days they should be good since you did not have them inside for very long.
