I have a shed and run now, so that is much easier compared to the hutch and run combo they had before, providing they are happy to be inside the shed.
In the hutch it was a nightmare when it came to the rain, wind and snow. I would get too cold after a little while sitting in front of the hutch. With the shed though I get some reprieve from the weather. I have already been sat inside the shed with them when it was pouring down outside, so when the winter comes properly a warm coat is all that will be needed.
I will keep spending at least a few hours a day with them
It gets darker earlier so I have stuck some of those LED kitchen worktop lights onto the roof for when the days get shorter. In all honesty I will just be sitting on the floor with them and playing a few games (hiding their pellet allowance, playing chase with the balls, sitting down with hay over my knees to encourage them to hop on etc)
I think that if you work out some interactive games you will be just fine. It's hard when it's cold, especially if you have to sit outside in the snow, but just spend as much time as you can with them. They will appreciate it if you take the time to play a few games and give them a bit of a fuss.
