I am feeding Pennfield Grower/Breeder, and some oats, barley and BOSS as a treat, i try not to give it to them till they eat their pellets they also get a little scratch but i try to make sure only the chickens get that. I just started giving them Kale and Collards, which they love, I tried grass hay and some really nice alfalfa. i try to just give them the leaves/flowers/dust lol and not so much of the stems but they don't really mess with it. Any suggestions for other winter greens or other stuff they should be getting. Also does anyone use or prefer Pennfields over Hubbards or vice versa? I can get both and are comparable in price but just want to give them whats best. I tried southern states but they would rather starve then eat it, it looks like kibble but the chickens like it so i guess i now am the proud owner of a 50lb bag of chicken treats. lol So pretty much what i want to know is which is better Pennfields grower/breeder or Hubbards or is there something better then the both of them and what else should they be getting or getting more of.(they are 2 and 3 and i'm hoping to breed them.
