I have four pairs living in three sheds, and this week I'll have two more fosters babies for socialising that will be in a hutch/run combo.
I only work two days a week, and volunteer work on a third day.
I spend pretty much all day doing bunny stuff, from feeding first thing in the morning, to clearing out litter trays and giving all four pairs separate suoervised access to the garden, preferably 2 sessions for each pair. They have their tea around 6-7pm, and the giants will probably still be out at that time.
They have their final night cuddles and treats at 10pm, and they're usually locked in their sheds then.
The only time I leave them is between 12 and 2pm when none of them want to come out as they all like their siesta.
I spend about 70% of my time in the garden, or in the utility or kitchen on rabbit watch.
