I got 4 BR chicks from the feed store 4 weeks ago. They were around 1-1/2-2 weeks old when I got them so I am guessing they are around 7-8 weeks old now. They were all supposedly hens but I have noticed one chick is a different color from the others (more white) and his/her tail feathers look a little different. I don't see a huge difference in a comb color or size but I am no way "trained" in exactly what to look for Maybe it's still a hen and they just are not purebreds. I have posted a pictures of the chick alone and with my others so you can see the difference in color (its very obvious) Any help telling me if I have a hen or roo would be great!
