I haven't had chickens before. If I do have chickens at some point I would start with a few full grown hens, mostly layer breeds. Once I get comfortable with hens and the hens get comfortable with me, I would then get 1, just 1 rooster so that I don't have many of the aggression issues that can result when you have multiple roosters.
Is this a good strategy for a first timer? If it is, great. If it isn't, then what is a better strategy because I am not sure that I want to start with day old chicks or fertile eggs and an incubator(I mean all the turning of the eggs, checking on the chicks periodically to see how they are growing, risks of having mostly roosters in the clutch including aggression towards me and the other chickens). I am also not sure I want to start with a pullet only order since again I have the risk that it is mostly or only cockerels which while they are nice and gentle in the beginning(sometimes even more docile than the pullets), when they become roosters they are most likely going to be aggressive.
