I add chicken manure/litter to the garden anytime!
Okay, so here is how I do it:
I don't like to weed! It doesn't amuse me, so I don't do it.
I don't like to water! It costs money, and even with a watering system set up, I still have to turn the nozzle "on" and then I have to return 20 minutes later to turn it "off". I rarely do it.
I don't like to add fertilizer! I don't want to pay for it and I don't want one more thing to do.
So, what do all my dislikes have to do with chicken manure being applied any ol' day? Well, when I plant, I lay newspaper in-between plants right up to the stalk (I start most things in the green house) and over top three or four layers of newspaper, I will lay chicken manure soiled straw.
The soiled straw holds down paper.
The paper covered with straw prevents the weeds from growing.
The zinc in the newspaper works a bit like an anti-bacterial.
The layers of newspaper provide a barrier between the soil and the manure and thus prevents the manure from "burning" your plants.
The "mulch" prevents moisture loss through evaporation AND it keeps the soil temperature warmer, which promotes growth.
I continue to add layers of manure/bedding on rows, hills, etc. throughout the season, throughout the year. The bedding (carbon) and manure (nitrogen) balance, then ages on top of the soil while easing my other chores (weeding, watering). In the spring/fall, the manure, bedding, newspaper get tilled in the soil.
I will also layer grass clippings (if I have them--I usually don't, as I don't mow--that's the job of the ducks and geese) sometimes a guy who mows yards for a living will bring his clippings and we layer that in-between the rows, the same as the manure. We also lay weeds from elsewhere in-between the rows. We allow the roots to dry/die of exposure.
(I also have seven worm factories at the garden, in addition to three more compost bins that are rotated throughout the year. I know some folks who put chicken manure and the red wigglers (Eisenia fetida) together. I see no need to do that, so I haven't tried it and I don't know if it works out. My worms job is to eat my kitchen scraps that don't go to the birds. The compost bins are for the compost that don't go to the birds, or the worms.)
