Ok, my birds have proven to not be the smartest..lol. I used Pine shaving when they were young to brood them in. Well I put the last bit in my make shift nest box and my older girl liked it but the young ones I noticed would eat some here and there and make a mess with it! Now the nest box is empty and I don't know what I should put in it. I am scared to put straw because of all the crop impactions I have seen on here and I know my birds will eat it. And if I put more Pine shavings they will just continue to eat that as well... What do you all use? What have you found works best for your birds?
