I have around ten roosters (maybe more). Some are around 4 months old and some are around 2 and a half months old. I can't keep all of them and I want to keep some for breeding. I will probably keep one of each color ( bl, black, sp, buff and white.) I want to create a checklist so that I can rate them as they grow and change so when it comes time to sell them this summer I can make an intelligent choice. Could I hear some suggestions for what I should include on this checklist. Thanks!
