I was about to write your new roost bar arrangements really seemed to have done the trick. Then this!Tonight's Roosting
This is a long video. it took them 15 minutes to settle everything. I feel most bad for Betty. I'm going to go out and put her on a roost myself tonight.
Aurora should be happy. She was able to harass everyone tonight.
One thought, it reminds me of some Buckeyes shenanigans, in that Hazel really controls roosting time. She won’t let anyone go up until Peanut has decided and indicated she’s ready to go. Then Hazel and Peanut go up. But Popcorn sometimes wants to go before then, and Hazel chases her away from the ladder. I believe I’ve seen her chase Butters off too. Maybe this is something like Aurora is doing.
