Chick Lovers,
Do you have an updated pic perhaps? Your original post and pics are about 2 weeks old by now (I think 1 week 5 days) so if you have an updated pic, that might give us updated things to look for. My BR cockeral, who looked exactly like yours 2 weeks ago and is his same age, has changed a bunch since you started this thread and I first replied. He really matured in 2 weeks, both how he looks (long tail, saddle feathers) and how he behaves. He's the boss rooster for sure! Fun to see him developing doing rooster-like things. Just today, he started something new. If any of the flock gets separated, he goes and finds them and does this little stomping dance to get them to move towards wherever the rest of the flock is. It's like he's herding them togehter. Seems like he's going to be a good rooster.
On the other hand, my 3 BR pullets pretty much still look the same as they did 2 weeks ago. A little bigger and more red coloring in the face but no bigger wattles or combs, pretty much the same in behavior too.
Guppy
