2022年2月21日 · The reason oyster shell and grit are often confused is that oyster shell is often called soluble grit. This compound dissolves rapidly in the hen's digestive system and is stored to be used later to make eggshells and support the overall health of your flock. Grit is insoluble, but oyster shell dissolves in the gut.

2013年12月30日 · Now sift the oyster shell with your strainer over a large bowl. The small stuff will be suitable for quail to eat. The large stuff left in the strainer is great for your chickens. You will end up with about one part quail sized to 5-7 parts chicken sized particles of oyster shell. Store it in a convenient location so it will be ready to use daily.

2018年2月22日 · However, if you want to avoid the oyster shell... you're likely gonna have to avoid "layer" feed that has it mixed in usually at a rate of about 4%. I use flock raiser with 20% protein and 1% calcium. I offer oyster shell (OS) on the side free choice for layers. Unmedicated starter and grower will both have less calcium and more protein.

2008年8月12日 · Hens only need oyster shell if they are laying (at this point it should be readily available at all times), or right before they begin to lay. And chickens in general really only need supplemental grit (I believe) if they aren't free range and are kept confined. If they are allowed to forage they should pick up whatever grit they need on their own.

2012年7月27日 · Yesterday I bought crushed oyster shells and mixed it in there food for the first time. I assumed that you would want to start providing it before they start producing eggs so you get good eggs from the get-go, however I have been reading that you should not begin providing the oyster shell until the hen has begun laying. Does it really matter?

2013年8月18日 · Most sea shells work, oyster is just easy to process and used to be a common and cheap by-product of the oyster fishing business; not so now of course. Reply Reactions: NagemTX , RedwoodCoastChick and Auntiejessi3

2014年12月1日 · I screwed down two margarine tubs to a chicken-level horizontal 2x4 in their (covered) run. One for oyster shell, another for grit. They sometimes bill out the oyster shell, but they do end up cleaning it up off the ground, especially when the container starts to get low. Just don't fill them up too full.

2010年11月6日 · Oyster shell just that - ground oyster shell - has lots of calcium, so yes there is a difference. I have been slack about giving my girls oyster shell and they still have nice egg shells. The key is they should be on layer feed - it has the calcium they need. Supplementation w/ oyster shell or their dried shells (like you are doing) helps.

2009年5月29日 · Oyster shell is put out to make thicker, stronger egg shells. Too much should have symptoms of calcium overdose and possibly egg shells with excess layers of calcium and bumps from deposits on them. Chickens will not over eat free choice oyster shell or grit unless they don't have enough feed.

2011年5月24日 · The feed that I get now, a game poultry conditioner, has grit in it. It is usually what remains in the bottom of the feed pan. So I just dump it on the ground. I have a seperate bowl with crushed egg shells and oyster shells in it. All the birds prefer the egg shell to the oyster shells but I leave them out regardless.
