Please tell me of the dangers to them re: grit? I have only ever had a "D" cup of very fine grit for them, but ...they demolish the eggshell and leave the grit........but was told to put it in. So, there must be something about it, as Tiels will not eat what is not good for them.
Yes, in Breeding season, I do boil eggs for them, but boil them for longer than normal ( another thing I was told ) and I smash up all of the whole egg, but only leave it in the aviary from morning till late afternoon, then I remove it........due to salmonella. I have to tell you I have not lost a bird from food poison ing ever. Have you seen the Bourkes Parrot? If you hae a chance, look it up, as I have them, they are fatter than a tiel but not as tall.
