I was nervous that she, and another just like her, were roosters after a fellow hen started to look like a rooster, and really must be. He has pointy saddle feathers and neck feathers. However, her (their) feathers aren't pointed, in those areas, just a little thin/disheveled?
Meanwhike, I will need to take a closer look at the one (of 6) that I was sure was a rooster. He might have rounded feathers? ...And isn't maturing like a rooster--his comb and waddles do not seem to have gotten disproportionately bigger over the last month(s)?
Two of six are hens, for sure. I think one is a sex-linked, rhode island and Jersey giant or similar. She developed coloring as expected from the time she was a chick, and looks like a sharp hen! Fyi, these were given to me from a school program hatch and they didn't know the breeds...
