These are from the TSC Assorted Bantam Bin. 12 weeks old, they are the smallest (slowest growing) Batams from the large batch I purchased. I can figure out all the other Bantams I have from that batch. All the other bantams are already in the Bantam Pen but these guys can still go right through the fence. despite being small They are very thick and meaty. sometimes they seem rumpless but the closer I look they just have a small Rump. When cornered they go into a chaotic spin motion until they have stopped spinning in a direction they want to run in to evade me even though I am just walking past them. Probably my favorite of the chicks to to watch run around because they are so full of energy.
