NO, they like to chew on them. They are Balsa. I am a retired Vet Tech of large and small animals for over 30+ years. I raised enough chickens and operated on bumblefoot myself, fix splayed legs. Processed my own chickens, cattle and pigs and lambs, even goats. My lil birds are fine
I trim their nails myself. PeeWee can't fly she uses those to jump hop I have them on the outside of my cages as well so she can hop up to the top of the cage for her observation curiosity. Sky is the same, when they are older I will remove them. Thank you for your input.
