So I've read and sorta understand how to grow fodder for my chickens (11 bird flock), but there are a couple of things I'm not understanding. 1. Do I need to buy any certain type of seed or can I go and pick up any type of grain? Will plain sunflower seeds (as in bird feed) grow fodder? 2. Once I have a mat of fodder growth, like I saw in other posts here, do I just lay it out on the ground for the birds to have their way with? The fodder I'm seeing looks like strips of sod, like you see if you buy zoysia for your yard. How do I feed it to the gang? Sorry if my questions are dumb, but I am rather new to this. Thanks.
