This is our first experience with chickens (and my first post!). We have 6 chicks from mypetchicken all sexed to be female, but this little one has me scared (no roosters allowed in san jose). They are almost 3 weeks old. She/he seems to have an attitude already and is the biggest of the bunch - we have six different breeds so I don't have anything to compare to. I know it's a little early to tell, but I just want to know what the professionals think. ;-) thanks!
