There is some controversy on that. Some say yes, some say no. I let Timber chew on plastic and it has never been a problem. His favorite toy is a blue plastic straw (has to be blue) from the convenience store. I see piles of little blue plastic shreds but none in his droppings, and he's never had a problem with it.
I was glad to read this. I have had Timber over 3 years now and have never seen what I would call a molt. Yes, he loses feathers throughout the year, but nothing like "molts" I have read about! Reassuring..
I can't really mimic Timber's contact call (not very talented). After he calls, I will just whistle. He will whistle back. I whistle songs to him and he will whistle bits and pieces back. He can make a pretty good stab at a few of them. It's actually a lot of fun.
What a beautiful baby! I understand your fears but know this, even clipped birds can catch the wind and be lost if they get outside. If they do manage to get outside, they are much eaasier prey because they can't fly to escape. I hope you don't decide to clip her. I rehomed Timber at age 5 and he was clipped. He is 8 now and hasn't been clipped since. He still doesn't fly. I'm assuming he never fledged and never learned. It is sad.
