If you can get them sexed it's better. I would say to just have girls. Have one boy and Adleast 3 girls or just boys. Blue swedish are the standard color but they also come in black and the less common splash. Make sure you have lots of room for them during the day and a safe place to sleep an night. If you have neighbors who complain about noise I would suggest all boys. They are very quiet compared to the really loud girls. They lay really well and as long as you get them young enough they are very friendly.
I live in twelve acres So the females wouldn't be a problem I decided that I want a balck male and female and two blue females
