The rooster is approximately 13-14 weeks old, the others are almost 10 weeks old They were almost 9 when I got them 9 days ago. They are still peeping a bit. But my gawd, I mean the rooster practically just stopped peeping! Seriously! The other two he was with matured at different rates, though there were from the same hatching. He was the largest, by far, but the other two probably only stopped peeping a week or two ago.
The other hen seemed totally normal. It was an arakauna (never can remember how to spell that, though I've had the breed forever). I did find her jammed into a corner the first day I brought her here and thought she had been attacked, but when I went to see and pet her, she popped up squawking and ran away. It was then that I thought "hmmm. better separate the roosters." which I did. I had been observing them a bit and believed it was the red rooster (which we killed yesterday) jumping on and pecking the hens.
(That behavior is to be expected, of course. What sealed his fate is that he was doing it to me, too.)
