Hello, I only have 2 hens at the moment - a Silkie and a Pekin bantam. They are 5 years old, hardly give me any eggs, and none at all in the winter, but they are lovely characters, and being small they don't destroy my garden when I let them out.
I wonder has anyone else ever had eggs with very thin shells? Yesterday one of them laid an egg with a paper thin shell, although today she laid a perfectly normal egg. Could it be a calcium deficiency? They have grit available, and get out into the garden most days.
Hi, tattiebogle (lovin the name)
One of the main causes of thin shells is when whole grains or feeds deficient in minerals and vitamins make up the bulk of the laying hen diet. So a good balanced layers feed is essential and a minimum of treats....in fact I would cut out all treats until the problem is resolved.
To build-up calcium levels you could also add crushed oyster shell to their feed.
Btw, all chickens 'cherry pick' their feed.
