Egg bound question

[Tiaris]

Plenty of direct sunlight & natural calcium supplements (cuttlebone, eggshells, fine shell grit, bone ash, fossil flour, oyster shells, canunda shell are all good ones) for the birds to pick at as they need them is the best preventative. If you still have egg-binding problems, then supplement with a good bird supplement with a focus on vitamin D3 & calcium (Vetafarm's "soluvet D3 breeder" is a good one) but I only recommend to use the supplement after trying the natural sources first & supplement only if you still experience the problem.
