The blackhead issue aside, can I brood 1 week old turkeys with 2 week old chicks and 1 week old guineas? I currently have a large fish pond acting as a brooder with the 6 chicks and 3 guineas in it. I was hoping to just add the blue slate turkey poults (3) to the mix. There is alot of space in the brooder. Thanks for your advice! Just to clarify, the large fish pond is just a really big plastic container that you could use in your landscape to build a fish pond.
