Chicken Breeders in Cheshire and provider of chicken keeping courses
This is a supplement to assist in getting good shell quality on your eggs.
If your chickens are producing poor quality or even no shells at all then they will need a supplement of calcium. Ideally via their water supply. This product coupled with a good diet consisting of properly formulated layers pellets will help to correct the problem.
Whilst shell problems persist avoid feeding apple cider vinegar or spinach, as this can be counter productive.
