reintroducing foods after hay only diet

hi,
my rabbits have been on a hay only diet for a week now due to digestive problems. i am supposed to be reintroducing pellets and greens from today but unsure how to go about this. what is best food to reintroduce first and what quantities? the hay only diet has really helped so i want to be sure i am doing best thing. thanks

I would start by introducing the pellets again, do it very slowley... How much pellet food did you feed before?

too many!! i used to give about 80g between 2 rabbits which i now know is too much.i gave pellets in the morning and i also gave veg at night. what do you recommend?

What age are your buns?
Jimby is around 18months old and he has only 1 egg cup of pellets per day (Half for breakfast and half for dinner)
