Calcium supplement for hen laying brittle eggs

[harmoncn]

I have a 2 year old RIR who has been laying brittle eggs for a few months. I have tried extra oyster shells, shrimp shells, egg shells and yogurt but have had no luck. I found liquid calcium at the hardware store where I buy feed, but it is labeled for tomatoes. Is it safe to dilute it and put it in her water? The product is Ferti-Lome Yield Booster (http://www.fertilome.com/ProductFiles/FL Yield Booster MSDS_1.pdf). Thank you!!

Here is the Material Safety Data Sheet for Ferti-Lome Yield Booster. http://www.fertilome.com/ProductFiles/FL Yield Booster MSDS_1.pdf Because of the precautions and warnings given for this product, including the warning to store this product in a locked storage area inaccessible to children and pets, I would not recommend giving it to your chickens. There is information if you search this site on vegetables containing calcium that you can feed your chickens, and I would suggest you try this instead. I will look for some additional information on high calcium foods and post more later.

Here is a link to a thread on this site that discusses foods high in calcium. https://www.backyardchickens.com/forum/viewtopic.php?pid=3761119 I have a hen who has oyster shell available 24/7 and she still lays thin shelled eggs. Must be her shell gland not working properly. Here is a link to information on internal and external shell defects, including thin-shelled eggs. http://www.thepoultrysite.com/publi...ndbook/16/thinshelled-eggs-and-shellless-eggs

Do they have access to crushed oyster shell at all times? If they don't they should.
