I think there are 3 roos and 3 girls in my gang of 6. They are about 10-12 weeks old and 3 have larger combs, while the other 3 have no combs. This is a pic of Big Betty she/he is much larger than she/he sisters. /img]https://www.backyardchickens.com/forum/uploads/94688_img_0062.jpg. Big Betty also likes to just sit like in this pic, while everybody else runs around chasing bugs. This next pic is Big Betty in the background and Chula is to the Left. Chula also has a large Comb. See what you think. Chula is also the peep that will always stand as Sentry when they are resting. The girl in the front of this pic is Jr and notice the lack of a comb./img] The">https://www.backyardchickens.com/forum/uploads/94688_img_0060.jpg The next maybe roo is Sophia, which is my favorite, and likes to be held.img][/img]https://www.backyardchickens.com/forum/uploads/94688_img_0057.jpg I hope the pics are posted correctly. Don't know how to post pics. FYI, I have a Mac.
