The Bird House Gemalen Oesterschelp 660 g / 500 ml

My finches finally stopped chewing on the cuttlebone and actually eat this shell—the texture seems perfect for them and the 660g bag lasts ages. It’s a simple, natural calcium boost that’s made a real difference in their energy.

I was worried about my cockatiel's egg production, but this crushed oyster shell has been a game-changer. The 660g bag is a great size, and she loves picking through it for the tiny pieces. Her eggs have been much stronger since I added it to her diet.

My budgie's beak looked a bit flaky so I added a spoonful of this to her dish twice a week, and it's already smoother after a month. The grains are a nice coarse grit, not dusty powder like the last bag I tried.
