We have two boys who will be two in January. They are currently in their hutch on the patio with a cosy bed in the enclosed part. It has definitely got colder these last couple of days so I'm wondering when they should come in. If they stay out as long as possible they will have more room to play in but if they come in they will be warmer and have someone in the room with them most of the day and DDog for company at night. They seem to be eating more of their hay these last few days too and I don't know if that is relevant.
