Hi everyone! Hope all is well in the BYC world! Was wondering how old chickens need to be before feeding scratch? The girls I have outside are a little over 3 months old and I've been throwing small amounts of scratch out for them to dig around and eat. Is that ok? Thanks for your help. Also, since they are outside, do I need to provide chick grit or do they get that from the ground? I don't notice any small sized stone "grit" in the dirt, but I'm sure there is some. Thanks again! PS..... They do have access to a sandbox, so don't know if that would qualify as some form of grit as the sand in the box is super fine.
