Thank I for expounding on that. I don't remember where I read it but somewhere I read that the layer feed actually has some grit in it. Is that true? Because that is what I was thinking when I told her oyster shells would b enuff. I figured they were getting some grit in their feed so a little shells would serve two needs. I'm a newby too. So am just learning maybe I should learn more before I advise. I've never given my girls grit...am I risking their health???? This is my girls home. Oh ya and "Redmans" home. I just expanded the run by a 12' section to accommodate some new girls and give them all more roaming room. Other than putting plastic around it to assist in keeping snow from accumulating in the run, do any of you hav any other suggestions I should do? ( not able to add electric so heated waterers are out of question, and hav enough birds they will b plenty cozy inside too. But I'm concerned with the roof of the run collapsing. Under snow weight...Help?!?!?!I just want to say that the oyster shell probably doesn't process food the same as "grit". Grit as it's packaged is usually granite and is much tougher and not absorbed by the chicken as Calcium but just passes. it may have some grinding quality initially while in the gizzard but I think it is pretty readily absorbed by the chicken. Somebody else might expound on that. From my own experience while watching my birds last winter...I didn't have grit readily available to them but had oyster shell. They weren't processing fibrous (greens) as well after a while. But after I got the granite grit all went back to normal digestively.
