I have ten hens (7 standard size and 3 bantams). They get free choice layer mash with oyster shell and grit. I give them about 1 cup of scratch a day. The scratch is wheat, barley, oats, little corn, wild bird seed, black sunflower seeds and fax seed all mixed together. They also get alot of table scraps with treats as in mealworms etc. Is this too much "other food" ?? or am I okay. thanks so much in advance!
