Well with day old chicks you can get girls only. (Pro) Hatching its a surprise with every egg (pro and con depending how you look at it) There are so many different reasons why people choose either/or. For instance, I love my EE's and would love to hatch them, they are relatively easy to hatch, but I DO NOT like the roosters, they are nasty critters, haven't found one I liked yet. (I think they are the devils spawn) that is why I order all girls, so I don't have to deal with the yucky boys. But also, I love the excitement of the hatching process, the last 3 days are the best its like Christmas and your b-day rolled into one. (pro)
You definitely get great exercise during that time (double that if you have stairs, again pro and con depending how you look at it) Chance's are that you don't even have to ask this question because you will end up doing both. Good Luck with your decision. Michele
