I was going to give some advice but looks like everything was resolved!
Prim always does a little bit of cute talk for 5-10 minutes when we put her to bed. It honestly sounds to me like she's re-iterating everything she learned throughout the day and practising talking "What are you doing?" and kisses. My problem is actually that she's so cute it's hard to resist cuddling her!
I have my own hand made version of a happy hut made with fleece and no thread, so it's super safe (since fleece isn't thready either). I think some people feel concerned that it will bring out mating instincts but I haven't had a problem with this. It's a bed time only sort of deal. I'm actually surprised your bird took to it so fast! Prim slept on the outside of her hut for a week or so before she dared to enter.
