So, I've always ordered straight runs and never had a flock of all males. I'm thinking of ordering the All Heavies Assortment from Murray McMurray (all males of heavy breeds) because it just sounds fun. Will I have problems with them fighting at less than 20 weeks? I don't want to order a bunch that will kill each other! I plan to keep them in groups of 15-25, if that's okay. The other option is to get the Heavy Assorted Straight Run, but that would still put a lot of males together. I'm sure to some of you this is a "duh" question, but I've never done all males!
