I have 5 chicks.1 Rhode Island Red,2 Buff Orpingtons,and 2 Barred Plymouth Rocks.They were hatchery sexed and so believed to be all hens.Little Charlotte,the small PR in the sun next to the Buff,I'm worried she might be a Chuck instead of a Charlotte!They're only 3 weeks old,but is her smaller size a possible indication that she's a he?This is my first flock,so I'm not as chicken savvy as I wish I was.
