So here's what I'm going by. See these two chicks. One has a prominent red comb and is starting to get wattles around his beak. I "think" that he's a rooster. The other chick (same exact age) has almost a non-existent comb and it's more yellow, and no wattle around her beak. I "think" she's a hen. What do you think? Am I right? I have no idea, but it's what I'm going by for now.
Bonus! Here's KT helping to feed the chicks this morning. We got to enjoy her company last night, as we had a "sleep over"! We had so much fun!
