Calcium or Vitamin D3 Deficiency?

Posted 31st March 2015 04:52pm by

A calcium or vitamin D3 deficiency can cause poor shell quality, but is quite rare in hens. If you come across this issue in your flock, here are my tips for getting your hens back in good health:

If your hens are have a good diet, with some crushed oyster shell they shouldn’t suffer from egg shell problems. However, if you suspect that this is the problem then you can supplement your chickens with vitamin D3. The easy way to do this is to save up your egg shells and bake them in the oven for 1 hour or until brittle. Then crumble them and add to your hens’ feed, you should start to see a difference in one or two days.

This simple method is a great way to give your girls their own calcium back without getting them into bad egg eating habits.
