I am in MA and not grain places around here that I know about. Making your own is interesting. Do you have a place to grind the feeds. will it cost more or less to do your own special grind.

I was reading online someone was getting their own grind so it was not medicated but was higher protein and desired for raising game birds.

I like letting them free range and using what is lower cost. Geese eat too much grain in my opinion. Geese actually do best on grass.

You can actually free range and feed them nothing. Just give them water. They will be probably better than with feed. Some people use a little feed or grain toward evening to get them back into the house. Just enough to get them coming home before dark.

Here is a link that might be useful: feed

henspa.com has a good organic scratch and lists ingredients. After looking at the recipe options at lionsgrip.com, it seems feasable to adapt the henspa scratch for a broader use. The henspa scratch is $15 for 50#.

I went to the henspa site and although I have not found the feed info yet I did find this neat garbage can tractor. I thik that is really neat for a subdivision chicken keeper.
