I bought a Buff Orpington (Magoo), and a Buff Orpington/EE mix (Mischief) chick last month. They were sold as being 8 weeks old, but after comparing pictures to my older girls at that age, I estimate that they are actually about 8 weeks old now. The mixed chick has a combination straight/pea comb, so I have nothing to compare it to. They are very close in body and leg size, but the comb on the Mischief is growing larger. At the time I picked them out, she didn't have an obviously larger comb than any of her flock mates, in fact, there were some in the group with much larger combs. Here are some pictures. They weren't cooperating! Magoo left, Mischief right Mischief's comb. Pinker and larger than Magoo's, but is it just individual variation or rooish? Side view. I know those almost look like saddle feathers, but in reality, they don't seem any longer/ more pointy than Magoo's. Some darker red feathering coming in though. Being an EE mix, I'm not sure if this is significant or not. Back view Magoo for comparison. She is being coy in this shot. Did I mention they weren't cooperating? Mischief personified!
