Skinny pigs take a lot of extra care and I wouldn't recommend them if you are a first time piggy owner. They are very sensitive to the cold and must be kept indoors. I have a thermostatically controlled heater in their room to ensure the temperature doesn't drop below 17 C. They have fleece hidies with more fleece inside them to sleep in.
I keep my skinny pigs on fleece and they have a large tray full of hay. They don't tend to burrow in the hay as much as my haired piggies but love to sit on top of the pile and eat it. I have also used Fitch paper bedding in their cage which was also good but I just find the fleece easier.
In the summer they can go outside in a run but you have to be very careful that they are out of direct sunlight or their skin will burn. Like all guinea pigs they should be supervised if they are outside.
Skinny pigs are very active and very vocal and bit hyperactive. They have a high metabolic rate and will eat more than your average guinea pig. This means that of course there is a lot more poo.
If you have any questions I am sure either me,
