We ordered 25 RI Reds from Welp hatchery at the beginning of November last year. We ordered all females, but lately we have started to wonder the sex on about 3 of them. They're just significantly larger than their sisters. I've attached a photo of one of the suspected cockerels and of the same aged hen (about 4.5 months old at this point). Any thoughts? Just wanted to see what people think before we email Welp. We've never raised RI Reds before, so perhaps these ones are just slightly ahead of the others? Thanks! Suspected cockerel...taller than the apparent hens, and significantly bigger comb and wattle at this point. Hen. Smaller (even though photo doesn't do justice) and much smaller comb/wattle.
