poo how many a day is normal

Just wondered how many is normal a day for a pair of buns.Been checking the hutches and saw that the buns are doing less poos but golden brown coloured.I cut them down on pellets as they was eatting too many and getting chubby so now its hay hay and hay every day with pellets every 2 days and veg 3 times a week and the poo seems a lot different is this diet ok x

There is no 'normal' for rabbits, as each is different, but you get to know what is normal for your rabbit. Poops should be dry and contain grassy/hay material.
Generally, plenty of hay and fresh water, a handful of pellets and a handful of veggies each day should be fine.
