The Buckeyes go in and out. Sit for awhile, then get something to eat or drink, then go back in. They might stay longer and sit tighter when somebody else wants to lay too though.But really not just checking them out by having a look - really going in and building a nest and sitting in there for 20 mins?
First thing this morning was definitely 'checking it out' - she popped in, looked around, went to the one next door and looked around - but that took less than 5 minutes.
