Thanks for all the replies. I am thinking that what I will do is order a crumble and then try the fermented feed solution. I do notice that they like moist foods a lot (yogurt, sweet potato, watermelon, apples) so I think a moist food crumble/grains recipe may work well for them. I have a lot of the organic seed feeds so I think I will do a 2:1 ratio of one of those and a crumble. More crumble.
I live in an area where the legality of backyard chickens is touchy. They are legal 1/4 a mile in every direction, and every neighboring town, but not in the 'village' where I live. I have about an acre of property, but my neighbor has reported me to the police. In light of this, I tend to give them a treat to quiet them down because when they see me they make noise. Otherwise, they are usually very quiet. Maybe if I lighten up on the treats they will be less inclined to yell at me while I am gardening. We are currently in the process of doing a zoning variance to try and get them legal. We also have been communicating with the mayor as the zoning is very odd. I live in the suburban back roads of town where it is not legal, but the houses in the center of town near and around our main street it is legal. In any event I am prepared to fight for my right to keep them. I don't think I could see myself parting with them.
