I have started giving 2 cups of scratch a night to our girls...we have 33 girls right now, buff orps. Is 2 cups too much?? My main question on this is that we use pine bedding in the coop and that is where I have been giving them their scratch to try to get them moving the bedding around more for us If they ingest any of the pine bedding is this going to cause problems??? We will also be adding straw once it gets colder outside but for now its just the bedding. Also has anyone here used aspen bedding? I dont know if there is alot of difference between aspen or pine but where we get our bedding they also sell horse bedding which is aspen...the pine bedding that they have had in the last few times has gotten alot finer...it doesn't stay nice very long so I was thinking of trying the aspen bedding?
