Does the pinking up of the comb come and go. I noticed yesterday morning that my 4 week old Barred Rock had a little pink to "her" comb. Really hoping that doesn't mean she's a he! But later in the day the comb wasn't as pink. And today it doesn't seem as pink (pretty much like yesterday afternoon and evening). Everything else has pointed to her being a pullet (early tail growth, clear spot on her head, speckled feathering so far instead of more distinct barring) So I was bummed to see the little bit of pinking.
