It was still all set up for a snake with a heat lamp and some rocks and logs in it. And it came with two bags of shavings! Cleaned it out and disinfected it and got it all set up for the chickies and now they have more room to roam and seem generally happier! Yay!
Here they all are basking in the heat below the lamp.
As of right now they are all sleeping in the sunlight beaming in our windows and I'm off to enjoy it myself!
