Concerning chicken manure...when I lived in New England we were deathly afraid of using it in our gardens because the "common knowledge" was that it contained copper residue and that the heavy metal would be bad for the ground and leach into the groundwater. Copper is fed to keep the shells hard enough for shipment. Has something changed in the chicken manure argument?
The wifey feeds our chickens a calcium supplement to help with the egg production. I forgot how much calcium a hen needs to produce an egg but it was a large amount. The big difference in our eggs vs store bought is the hardness of the egg shells. Our hen's eggs take quite a bit more force to crack open than store bought. I would be surprised that copper would help harden an egg shell and even if it did that it would be cost effective compared to other supplements. I think the supplement we are giving the hens is limestone based. It really would shock me that limestone would be less cost effective than copper. Hopefully another TBNer will have some information.
When I lived in FLA there was a story about some land that had been owned by a very old couple for many decades. They raised chickens and used the manure to improve their garden soil aka SAND. :shocked::laughing::laughing::laughing: In that area of South FLA the soil was just sand but the photos of the soil in the garden showed wonderful black soil. The couple lived into their 80s-90s eating out of that garden.
