I have three 7 mo pullets (fairly sure and will try to get pics on here but my computer deleted my only attempt at downloading vids from card reader so terrified to try more) and they're all mutts (different mamas too) and when I got up this morning I heard the only roo I have (3 years old) then I heard obvious new attempt at a crow sound. Very cute but unexpected! And I know these 2 pics are useless in sexing but this is the only 1 of 3 I haven't watched lay an egg yet. I will separate "her" tonight and see if she lays in the next few day. And I know some girl chx can crow but this will be a first in 13 yrs. of my keeping chx.
