So the chicks are just under 4 weeks old (the right one slightly older than the left I think, but this is just guessing, could be a few days off). I strongly suspect I have one rooster and one hen. Different mixes so its comparing apples to oranges...but even so.
Waiting for the DNA test to...
I got 2 fresh chicks from someone who has a gazillion chickens running around her yard. One is just generic darker yellow/orange without any clear markings yet, but the other seems more distinctive. It has "eyeliner", and was pale yellow with vague chipmunk stripe type things when I first got it...
