Well I just took a good look at my GSL supposed pullets from Ideal tonight and well to my surprise, I was alerted to the fact of Gold Sex Link male chicks being mostly white and what I thought was a pullet is actually a roo I guess. In looking at him closely I guess he is a roo with a bigger comb and beginning of wattles too ..; AAAAAHHHHH and if that is not bad enough----- I looked at my RIR's and guess what? Please tell me that pullets develop wattles and big combs at 5 Weeks of age!!!!!! Yeah that is what I thought. So out of a order of 6 chicks, from Ideal, 2 GSL's, 2RIR's and 2 BR's that are all supposed to be pullets I got two roo's . I am soooo bummed as now I have 2 to rehome as I can not have roo's. No chance that pullets can have well defined and showing wattles at 5 weeks huh?. Help Me!!!
If the RIR you are questioning is the one standing behind your sex-link in the other post, I would definitely say that one is a roo. But of course, you never know about the sex-link, it's possible it is a light-colored hen. I have seen a couple pictures of sex-link hens that were much lighter than most of the ones you see. I would wait a little while and see how everything develops just in case.
One of my golden comets remained buff and she is definitely a pullet. Apparently some of the females express only a bit of the gold gene in the cross so don;t give up on the golden comets yet!
