One acre.....How's the new litter doing? Have you been taking the nest box inside? It has been hot here in Indiana (over 100) near my cages. I can't imagine what Texas is like. I lost 3 of 9 bunnies to the heat early last week while I was camping. The care giver only looked at, never handled, the bunnies so I found three little piles of "empty fur" when I returned. She didn't replace the ice bottles or count the exposed kits.
