This was helpful to me as well. My chicks still have some "fuzz" and are not yet full-feathered. My complete lack of chicken vocab will certainly out me as a completely new chicken person. I think mine are 6 weeks ish old.
I am purchasing a home with a little bit of land and want chickens. I am looking for local to me "Chicken People" and or breeders :) I am looking on Youtube for information and love to connect and talk to people familiar with chickens to help select the "right" ones for me.
