I am new to this chick stuff and I have my first hens that are about 13 weeks or so. I forgot what kind of chicks I have but I have 13. There are all different kinds.
This is a great place to learn just about everything there is to know about raising chicks! Because there are so many members, literally all over the world, someone is available night and day to offer advice.
And, if you can post photos, there are folks who are great at identifying breeds.
