All of our chicks are 10 weeks old and peckers is the only one that looks different, I am hoping she is just going to be unique! These are some of the pictures I took of Peckers, if you need a different view let me know I have a bunch more! Roo or Pullet? She is the same size as the rest, just darker and feathers are a little different, she is also the only one with the fluffy face, she isn't aggressive towards the rest, if anything she is more docile towards the rest of the group. TIA!!!
