The girls are always in their shed at night, and a hutch within that. The top level of the hutch has a blind that comes down and they also have their sleeping compartment stuffed with hay. So no tarpaulins but they did get their snugglesafe back on Friday night when it went down to -1.
Kenco & Fay have a bigger indoor space so they have their shutters on, plus one tarpaulin over the front, and a snugglesafe still. Will probably leave the snugglesafe for the next few days as the night temps are set to remain mild, but there is forecast another chilly night this week, cant remember which day, so will give them the snugglesafe back again then. When the nights start to be consistently warmer I will stop putting the covers down and they will just have their shutters. I think its important they have that to protect from seeing foxes and vice versa as well.
