My Golden Lakenvelder hen survived the winter eating the dry cat food I put out for my 5 outdoor cats. Until I built a coop and added other chickens to my flock. Is it okay to feed hens dry cat food occasionally? What are your thoughts on this? I basically feed them layer pellets, some worms from my worm bin (red wigglers for compost tea) and sometimes freeze dried mealy worms mixed with oats (Chicken Treats in a package from Coastal Farm Supply).
