Have you found your buns don't nibble them then, that would be my only worry, I'd love to get something like this for my aviary run but, Ness is a bit of a nibbler, Jingle (rex) is OK but, I spend a fortune on hay for the floor - although saying that I just use the cheap stuff from the Range and put their decent hay in a basket to eat - what have you found people with these ? Are they not nibblicious to buns:lol:
