The book about chickens that I got for my kids says that 1 roo and 2 hens are a "nice little family." I have several little families of different breeds that are/will be 1 cockerel to 4 pullets (they are all pretty young still and a couple of cockerels are in their eggs at the hatchery right now). Is this going to be a disaster? Should I get more pullets to offset the ratio? What in your experience is a good ratio?
