Correction, the chicken manure I have access to is what I'm referring to. Others I would suspect and/or hope are a lot safer to use.
Before chickens are put in the houses the litter is treated with this stuff called plt (poultry litter treatment) it's sodium bisulfate, that reduces ammonia levels and pH of the litter, basically an acidifier. It claims to increase the nutritional value of the litter, and is only used in 50% of the house on the surface. But then there's other things sprayed throughout the whole house, insecticide mostly, pyrethrin, boric acid, and something else im not 100% sure that the mix with it. The boric acid is a powder. Then you have the chicken feed itself that the chickens eat, God only knows what is in that.
My reasons for not using it a whole lot is strictly my opinion. I'd like to have it analyzed really. I could be sitting on a gold mine lol The bulk of it does get sold for fertilizer, but it goes through a process before they use it. Either way a little goes a long way anyways, with that shit (no pun intended) I use it but not excessively. Typing this and thinking has me thinking I've most likely consumed worse and put worse on my own food and smoke somewhere along the line. I did start with miracle grow, until I found out about other nutrients and Monsanto. Anyways I just wanted to clear that up, that this is my opinion about the chicken manure I have access to, it wasn't about any store bought products. I'm not familiar with them much and can't speak on them. I think the best approach if it's something you would like to use, is buy some chickens let them live free range, and either put down plastic and allow them to shit on it for awhile, which is easy, they shit everywhere all the time lol There was a show that came on called Farm Kings I used to watch and they had a big pen on wheels, they put a few dozen birds in there and moved them every couple days or so on the land they prepared for growing, so that's an option as well I guess. Good show too, think it was canceled though. Not enough drama for tv I guess lol Anyway just wanted to clear that up, didn't expect to make such a long post.
