I purchased this chick (along with others) direct from Meyer hatchery as a day old sexed pullet. I already have one for sure 'oops' cockeral (https://www.backyardchickens.com/forum/viewtopic.php?pid=6892483#p6892483) and one of my barred rock pullets has me concerned! I have two BR pullets and they look identical (color, body and feather shape, etc) except the comb/wattle color. Chickadee has all of the signs of being a lady except this week her comb and wattles started really turning red. I know that they can 'flush' or blush when the chick is hot but hers is staying quite red even when it is cool at night. Her body shape, posture, and colors read as 'pullet' to me. Is there a chance she is just developing faster than the other BR I have? I have read that rocks comb out fast. Am I giving myself false hope? This is Chickadee as of today, at 70 days (10 weeks) old. All the same chick! Thank you for your help.
