I have been reading this site on and off all day picking up lots of useful info. (really enjoyed looking at pics of all your aviaries too). I have 2 questions that I haven't found covered.
The roof of our aviary has a square corrugation. Hope that makes sense. Bumps essentailly with a gap of about 1.5cm squared. Should we worry about a bird escaping? If so, what can we use to block it up.
Now an easy one! What size dowel is best for the perches?
Thanks
Nic
