Hello out there! The hubby and I are excited and eager to get started with our new flock! We have two little girls who are equally excited. We are leaning toward Indian Runner ducks and Orpington chickens. Just about 4-6 of each. What do you think about getting a few different breeds to start? I have read and been told that it's best to start small and start with one breed. Also best number to start with? Opinions?
