My home made diet includes- Producers Pride 'All Grain', & whole corn, whole oats, soybean meal, some Manna Pro rabbit pellets, and Manna Pro Oyster Shell. Dose this mix contain enough nutrition for my 7 hens? I also give them a vit./min. & electrolyte supplement in their waterer every Friday and Saturday. They LOVE this mix. The P.P. 'All Grain' contains- Whole grains (Barley, Corn, & Oats) and a lil molasses and salt too. I calculated out its protein to about 13.5%. Is this diet okay? My 7 girls wont eat ANY brand of chicken pellets but are doing just fine on this diet so far. The winter is coming to Atl., Ga, so I'd like to know if they'll fair okay with the cold weather.
