Best food to fatten chooks for eating

[ChickenKeep01]

My family and i have just eaten 3 bantam roosters and there wasnt much on them, and im planning to eat the other 3 as well seeing as they are crossbreeds and unwanted so im just wondering whats the best food to fatten chooks on.

Thanks in advance.

You don't want to "fatten" a bird that you want to consume - you want to build muscle tissue. Unfortunately, the birds you are working with are not designed to build or carry that sort of muscle mass. Protein builds muscle - this is why feed designed to develop and finish meat birds is rich in protein. At this point, though, depending on age and the crosses involved, there likely isn't much to be done to make the birds you have do what you want.
