I was looking into buying On Time's S-250 Quad PodFeeder with On Time Solar powered unit. I have two questions. Can I use 50% corn and 50% Oats with a spin type feeder like this? And Will the solar/gel 6volt setup stay charged thru the cold winters if the NE or should I expect to recharge that battery on a regualer basis ?

I want to use a mixture of corn and oats/pellets so the diet is not all starch but some complex carbs and protien. Any help would be greatly appreciated!
