I am not an expert, but your chicken looks like a pullet to me.
I don't have a lot of picture of the girls when they were at that age, because I was frantically trying to finish up the chicken coop. Six growing babies in the house was getting very stinky.
Thank you! You're too I couldn't help but notice the similarities. Kitty is 7 weeks old now. I notice her comb is flat and still the same shade of pink. How old is yours now? I'll update a picture tonigh5 when I get home and maybe we can compare since I only have one SLW and nothing to compare to
