In reality, the wisdom of the old is greater than the inovations of the youth. Quite simply, the old farmers had it right. You have a few chickens, and feed these chickens tablescraps and other things to keep them alive during the winter. When the spring, summer, and fall arrive, you have a fenced off section in order to protect the chickens, and you allow them to feed themselves. This is really the only practical way. Am I really going to grow and store 2500 pounds of potatoes? Probably not...
The deep litter is absolutely necessary imo, lots of different organic matter, and a rather large coop. The rabbit thing... rabbits are a good idea, especially if you have goats (like me) because the rabbits will eat the parts of the hay that the goats will not. However, rabbit manure is not a problem. Rabbit manure is very valuable and doesn't burn crops/trees. The regular meat rabbit cages are made of wire with a tray underneath to collect the manure... so having your rabbits above your chickens actually does you no real good. Worms you may say... but chickens will demolish any worm base before they even get started. Chickens do eat rabbit poop... I don't know if that is an advatage or disadvantage. I do have one cage without a tray underneath, and three cages stacked on top of eachother with trays underneath. Rabbits poop a lot, if I had all four cages without bottoms, then the coop would shortly be over run with manure. Also, by using the trays I dump the rabbit manure into a 5 gallon bucket and it is easily brought to my trees, about once a week. Having all of the rabbits over the coop would take away this benefit. The "problem" of rabbit poop has already been solved, by using wire cages and trays... taking away the tray solves no problem... because there is no problem. Also, you don't need to buy a book to tell you about rabbits pooping in your chicken coop (Saladin), it is not a difficult concept to grasp.
It is sad, that in todays world we have to work so hard in order to have chickens, goats, rabbits... the things that were in the past the mark of a poor man.
As regards the "experts" who say that people can not have a hot compost bin without chemicals: Old wise chinese man say "man who say it can not be done, should not interupt man who is doing it." These "experts" apparently do not use chicken poop...
Also, politically correct woman who say that man should not use the word "man", but rather "person", should also not interupt man who is speaking.
