I finalized on feeding either corn mash, which is almost like powder, or feeding crumbles, usually both combined with a little bit of scratch grain. My chickens waste pellets like crazy, digging through the pellets for something else, apparently, and leaving them on the bottom of the coop floor by the ton.
Actually, my having tons of waste from pellets is a significant exaggeration, since I only have (5) chickens: (2) barred rock, (2) buff orphington, (1) silver wyondotte. But, they leave 50% in waste, more or less, when I feed pellets.
I also provide crushed oyster shells, and gravel for digestion. I am only able to free range them occasionally, due to predators in the area, dogs, hawks, etc...So, most of the time, they're spending days in the coop, aviary, and scratching around in an attached 20' x 20' square shaped run that attaches to the aviary.
You know, I can remember as a kid picking up chicken manure for the garden for my mother and grandmother from a local farmer. I notice these days that the chicken manure I'm getting doesn't look anything like what I used to see at the farmer's chicken manure pile. Just wondering why the difference.
Did the farmers 50 years ago, or more, feed something other than what's commercially available at the feed store these days? Is it because the farmer's chickens free ranged almost constantly before going to roost at night, thereby getting a more natural selection of varied food sources? Is it because the chicken manure was older, and had started to break down more than what I'm seeing from my own relatively sparse accumulation in comparison to the farmer's big operation. I'm not referring to the commercial kind of chicken farmer of today, but the "REAL" old time farmers, with large flocks of chickens, cattle, goats, large fields, corn, beans, vegetables, etc...But, not the assembly line, modern day operation, but the "old-time farmer."
I recall the "old-time" farmer's chicken manure looked nothing like my chicken's manure, but being almost black or very dark brown in color, but dry, almost like clumped crumbly coffee grounds. There is a texture difference between what I used to obtain from the "old-time farmer," and what I see from my chicken's, which when dried out is rock hard, and dark gray to medium brown in color.
I've been dumping it on the garden when I clean out the coop, for the last year or so, but I'm not sure I'm getting the same benefits. My grandmother used to say that the secret to a good garden was chicken manure, not cow manure. But, she was from the "old-times," and I suspect things have changed dramatically compared to the norm in her day. Unfortunately, I can't ask her any questions now about the past. She's been gone for 10 years, gone at 102 years old.
