If you are going to start with chicks and raise them, then it is going to be more than 10 minutes per day to begin with.. after they are feathered out and about a month old they become less work.
My gut reaction to you is, do not get any.. just your hesitancy to spend time with them tells me you do not have the time to spare..
sometimes emergencies come up with chickens that take a lot of time.. will you have extra time then?
read through some of these threads and put yourself into the situations you read about..
eventually you will get more involved and then you will be spending more time with your chickens....It is ot a matter of choice,, it just happens.. then, will you be willing to spend more than 10 minutes per day??
It takes me close to an hour just to feed and water my birds each day.. I started out with 7 pullets "just for eggs"..
I have in the neighborhood of 100 assorted species and ages of birds.. turkeys 29. laying hens 60, geese 3, muscovy ducks 5, guineas 25. I just recently got rid of 9 ducks, 25 quail, 300 guineas, 15 chickens, 9 geese... is this what you want??
