We have been wondering when we could really tell what gender birds we have. Well, for some of these guys, we're on week 4 and it's becoming obvious. These are the 7 guys that hatched around election day. We saw reference to UC Davis Veterinary Care Program, and found their page that gives the following info: 2. Physical Characteristics (4-6 weeks of age) a. Comb The cockerels comb is medium size and pinkish, the pullets is small and yellowish. b. Legs The cockerels legs are sturdy and long, the pullets are finer and shorter. c. Tail The cockerels tail is stumpy and curved, the pullets is longer and straight. d. Back The cockerel has a thin line of stub feathers down the center of his back, the pullet has more advanced feathering along the center of her back. e. Side of neck, flank and crop The feathering in the cockerel in these areas is poorly advanced, the pullets feathering in these areas is well advanced. f. Wing bows In the cockerel the wing bows are bare, in pullets the wing bows are covered with small feathers. According to this, we can determine the following. Rhode Island White Roos (2) Combs - Much larger than the hens and beginning to turn pinkish Backs - Thin line of stub feathers Wing bows - Bare Rhode Island White Hen (1) Comb - Way smaller than other two RIWs Back - Fully feathered Wing Bows - Covered in small feathers Easter Egger Hens (4) Back - Fully feathered Wing Bows - Covered in small feathers I'd bet on the RIWs being right, but the EE's are a little harder to tell. There is just 1 that I think could possibly end up a roo, but hey, if they are all hens? I'm happy! I already know I got 8 EE hens from Ideal, and 6 EE roos. That would bring a total of 13 hens and 8 roos. Then I have the 5 fridge-babies. I have a feeling at least 2 if not 3 of those are going to turn out to be roos. Keeping my fingers crossed for more hens!
