I know you may want to use chicken manure because its free, but bat guano or seabird bat guano would probably be a more effective way of making a tea ( they are a bit higher in either phosphorus, or nitrogen) just depends on if your making a veg tea or a flowering tea. Obviously for veg teas you would want to use the seabird guano, worm casting, a form of seaweed extract, and maybe some molasses. For flowering use the high phosphorus guano, worm castings, no seaweed extract, and definetly molasses. Some people will add a few other things, but I would say these are the most common. My plants LOVE this stuff. Just make sure you get a proper mixing ratio and still check the PH. Ive burned a few leaves when I first started using these teas, but that was from too much nitrogen (seabird guano) and or too strong of a mix. Good luck and happy growing. Oh ya my orginal point was these bags of guano are like $13 and should last quite awhile. Always aerate the water for a day or two. Then let settle or strain it and feed!
