I determined several years a go if I did not use wire floors in my brooder box would not have a problem with cocci. If you have wire floors just dampen some news paper and lay over the wire . Put some feed right on the damp paper. I have not had cocci since I started doing the brooder like this. I raise several hundred show fowl eack year. They will become immune to cocci with this method.
Sorry, bu this makes no sense for the control of cocci. Chicks get Cocci from having contact with feces, often from used litter and the feces from previous flocks, that is contaminated with cocci. When people raise chicks on wire it is to prevent the exposure to cocci while they are young. So what you are saying is you raise them on wire and then add wet paper to try and encourage their exposure to coccidiosis? Even then they will only have exposure to coccidiosis if the birds themselves already have it. If they already have it then adding the wet paper is doing nothing more than helping them find feed. Just curious what your thought process was here.
