Being a newbie chicken parent, I had hoped my 6 mixed chicks would be calm and enjoy being held. At about 7 to 8 weeks old, 3 chicks stand still and allow me to pick them up by placing my hand under their chest, from the front, and lifting their body gently, feet dangling. Two of them I have to kind of surprize, pick up from the top, pinning their wings to their body. My biggest one, a white Plymouth Rock (who looks and acts suspiciously like a roo) has a fit, fighting and flapping when I pick her up. She is also nearly impossible to put back into their "brooder" after free-ranging for a while in my basement every evening. (Outside coop not finished yet!) This evening she fought me when I tried to hold and pet her, but I kept her on my lap, with her giving me the stink-eye all the while, to let her know I was the one in control. Then when I had to catch her to put her to bed, she had a royal fit. I held her upside down by her feet for maybe 15 seconds, till she was calm. She remained calm after I turned her right-side-up, and then put her in the pen with the others. She weighs about twice as much as the others, and is the flock leader. I don't know if I did the right thing or not, but I felt she and the other chicks needed to know I am the boss. I was gentle, but I really felt like wringing her neck! I almost hope "she" does turn out to be a "he"--that will give me the excuse to send her to freezer camp. I am totally amazed at the difference in personalities of these girls.
