Bought these chicks two weeks ago, and was told they were about a week old. So now these little ones are about 3-4 weeks old. I have three Delaware’s, which I am pretty sure is correct according to pics on BYC. My question is the black one. I was told by the feed store that it was a ROCK but they never specified the type. From looking at the pic at the store it looks like a Barred Rock, but my little chick just does not seem like she/he is from her age. Can anyone tell me what she/he may be? When we first brought them home the Delaware’s picked at her like she was an outsider, now she seems to rule the brooder. They do not beat each other up but they defiantly move away from her at times. She is also the only one that will roost on the stick at this time. She is also very jumpy and does not want to be close to us or held, except in the first pic when the electric went off and no heat lamp, they needed warming.
