Welcome to BYC it is not a good idea to have sillies as their feathers are not meant for cold and or wet conditions, other options for friendly chickens are polish, barred rocks, austrolorps, cochin, marans, wyandottes, orpingtons, buckeyes, chantecelers, brahma, delaware, dominique, RIR-rhode island red, newhampshire red, sussex, welsummer, white sultan, ameraucana, cream leg bar, easter egger, salmon faverolles, swedish flower hen, These are all different egg colors from dark brown to white, blue to green and there are some feather footed breeds but it depends on what type of run you have because feather footed breeds aren't good with mud, and as a rule if you don not have a protected run white breeds are usually the first to be picked off, and i gave you some options with beards muffs and head poofs and those aren't good with predators either but can sometimes get picked on.
