Since I bought sexed chicks, I just assumed that I'd have all pullets. But after reading this forum for weeks, I have learned that it's definitely not a 100% thing. I haven't seen any "roo" signs in any of my 4-5 week olds, but then I looked closely at my Welsummer. She's about a week younger than the others (give or take, I believe she's about 4 weeks) but her comb is the largest and most pink. I don't have another Welsummer to compare her (or him!) to, so I don't know if I'm being paranoid or if she is indeed a he. Any help would be much appreciated! I'd really love for this one to be a pullet since it's my only one.
