Chicken manure is infamous for burning plants, never use that shit. The best thing to get is a basic potting soil with no nutrients added. I would say my favorite soil would have to be Black Gold All Organic, then Black Gold all purpose, and finally whitney farms potting soil. Just get a basic soil and it will be fine to use by itself for the first couple weeks, then slowly start to add nutes. You could also by some compost, NOT manure. Good compost have bat guano, worm castings, lime, and composted organic matter in them. You could mix this with your soil at about a 2:1 or 3:1 ratio. 2 parts soil 1 part compost.

Right now i would pull your plants and wash all soil from the roots then carefully place it in a soil like a i described above.

And after you transplant leave your plants alone and don't touch them, let them recover...
