Farmchiq, hardware cloth is the little metal wire that is on the bottom of your incubator. It is used for many things and is wonderful!! No idea why they call it cloth, cause it certainly is not made from cloth, but wire, smiling.
All my coops have 1 inch poultry wire, a bit higher quality than I used to use on the coast, kind of sturdier. In the areas where there will be chicks, that like to go through 1 inch holes, I have 1/2 inch poultry wire that goes up about 2 feet, they can't get through. All of my coops have 1 inch poultry wire. Some of the outside pens have chainlink fences that used to be a dog kennel. They are wonderful and are used to border my buckeys and cochins. Other than that, this wire is good and it is strong. Have a most beautiful day, CynthiaM.
