Making a wing

Good evening ,

Our friends Oscar and Frida enjoy very much a wing .

We bought them at the beginning a plastic one but after one week was broken !!They made it in 3 pieces .

Then we made a new one using a small chain and eucalyptus stick . They enjoy very much chewing the eucalyptus wood and after 10 minutes the wing was also destroyed !!

Finaly we used olive tree stick and the wing is still there!!

They also manages to climb verticaly on the chain!!
