I am not letting them go, I just think they want to fly outside, the only toy they play with is this one with strings they can pull on. Lately, they've been eating their perches (wood,rope) and they finally started using the cuttlebone too. Is it normal they're pecking at their perches, because the wood is coming off and they're tangling up the rope perch. Also they've been rubbing their face on their ladder and perches, is it just some bird thing or is something wrong because Paris never did this before
