hello @chickenbreederinchina , welcome to BYC 

Yes I do, have been for a few years now. I've written about how I do it here with an update here https://www.backyardchickens.com/articles/wholesome-homemade-feed-2.79307/.Just wondering if anyone else here is making their own feed
Yes it does. What you are using is carb heavy and protein light, and you really want to get more variety and balance into their feed before they start to moult.I’m also curious whether this kind of homemade feed needs extra supplements to keep the hens healthy in the long run
