In fact, they die from it.
Our grower rabbits are in movable tractors on grass but our adults are in raised hutches to help generate manure and compost for our gardens. We deliberately placed the hutches on the north side of our barn so they would only get sunshine in the morning and would be near the chicken house so the chickens could stir the rabbit manure/straw mixture into garden compost for us.
Unfortunately, it wasn’t enough.
Even though the rabbits had plenty of water and were in a sheltered location, we lost 6 rabbits to the heat today. It’s been over 100° F for over a week now and I think it was just finally too much.
We moved all of the hutches into the barn. It will be cooler in there but there will also be less sunshine to sterilize everything.
This weather needs to break soon. If this is June, I’m really not looking forward to July and August.
