Hi I am new to the site and have 3 x gorgeous 7 week old mix breed Runners (2 F and 1 M) who I have for the first time have them play on their home made pond which is also situated inside their run. (They have taken to it like 'ducks on water'). I noticed though that they have slept on and around the pond (on the boulders) all night. Is this ok? They don't like to sleep in the house made for them either since day 1 of being in the run? Am Just a worry wart? If they happy should I just leave them to do as they wish?.... I would love some feedback and suggestions? PS their run is fully enclosed and roofed (this is a pic the boulders weren't yet in the photo but they fully surround the pond).
