hi i have some very good Amish made chicken layer mash it works. ill start by telling you my story. my ladys will not lay on layer crumbles in the winter. i went all last winter feeding them and no eggs. they are in there pen with covers over the windows, but all day there very large door is open witch allows plenty of light in.they are pretty much free range but sleep in there pen at night.so this winter i searched hi and low, and Finlay i found this blend of feed and it really works. the girls are laying at about 50-70% every day. i havent used this feed in the warmer times yet but its doing good now! so if you are close or even not so close i can provide you with feed "layer mash" its 13.50 for a 50# bag or 12.00 for 4 or more bags at a time. you can call me 1-814-966-3519 or email me i am in duke center pa. 16729
