That means nothing, really. At this age, even a pullet wouldn't have an ounce of mothering instinct in her.
as you do not know my chickens or have seen how they interact with any of my other birds.. I suggest you leave comments like that to yourself.... there’s also the way she moves how petiet her body structure is my own personal research.... while she doesn’t “sit” on the ducklings she does have a strong sense to protect them from the other chickens (and ducks).... her full size (as she is today) she fits in my hand.... and from doing my own research a rooster (or cockerel) would have much larger wattles and a very red comb.... not the rose pink of hers....
im taking her to the vets tomorow to get her sexed.... will update when I get home.
