|Message:||I don't know how much help I am, but I'd like to point out that Chloe is only expecting the same level of commitement from you as she would from her Nanday mate. Nandays are extremely social. When they pairbond, they are together 99% of the time. A tightly bonded pair are more like a bird and his shadow than two separate birds, they do everything together, at the same time. I see a lot of simultaneous displays, yawning, stretching, fluffing, and of course screaming. Chloe may have learned how to behave with a nanday mate, but all these behaviors are not working well in your situation. She's only doing what she learned from her previous home, and apparently, they must not have taught her to entertain herself.
Another thing is that my adult birds don't play nearly as much as the babies. The young ones get really silly with their toys and play all kinds of weird funny games. The adults do things centered around everyday life - chewing, nesting, foraging, bathing, travelling. They like to do stuff, and for most of them a hanging toy is boring... Fresh branches for chewing are a great hit around here, so are food toys and any other food-related activities. Maybe Chloe would like a toy where she has to work for food? Or a safe branch, to chew leaves and bark? Have you tried to teach her to play by SHOWING her how to play with toys?
Also, how old is Chloe? A couple of my babies have gone through a skittish phase right around a year of age. I made the mistake of fussing over Senna when she did it, so she adopted a "phobic" response to certain situations. She was not actually phobic, but she figured out that by pretending to panic she could avoid certain unpleasant activities. Later, when Bailey went through the same skittish phase, I totally isolated and ignored him, unless he begged to come and join whatever I was doing. He got over his skittishness fairly quickly, although he still is not very social with strangers.
