i just finished...yes the gates are frozen, but good thing i went out because bunnies had already emptied the fresh water bottle i gave them this morning!! i put the thawed one on and refilled the 2nd so hopefully they will not run out again before i venture out in the morning!
Yeah mine were so cold lol also I took my gloves off so that might be why lol the shavings were sticking to the gloves so I took them off to put shavings in the little coop which took a while cause the door was still up at first/wasn’t sure I wanted to use the whole thing so I put them in bunch by bunch lol then finally decided to take it off and dump the other half in.

And oh wow that’s good you checked! Their water was frozen too. Need to buy another heated bowl for them hahah
