Natures Grub Oyster Shell
Natures Grub Oyster Shell is a medium sized Oyster Shell suitable for all adult birds. Oyster Shell provides the essential calcium required for healthy bone growth as well as strong eggshell production.
Packaged in a handy 1.2kg Pouch.
How do I feed this? Oyster Shell should be offered from an additional feeder as your birds will regulate how much they need all by themselves.
