I have 4 hens that I bought as day-old chicks and raised as usual with the heat lamp and all. I also have 2 chicks that I bought as day-old chicks and gave to my broody hen to raise (which she did very well) I notice a big differance in the attitudes of the 2 that were hen-raised. They tend to stay together with each other but they wander off from the other 4 a lot. (My chickens are very free range, but get locked up at night.) These 2 have also found a place outside of the coop to hide a nest, and although they are kind of friendly, they are not as attached to me as the other 4. When they were little chicks still, I had daily contact feeding them, etc., and I would pick them up once in a while, but not as much as the first 4 that were raised under the light and knew that I ALWAYS brought food. It isn't like they were totally wild and never saw a person!They don't really seem attached to the hen who raised them either. I just thought this was interesting and decided to share, has anyone else noticed this behavior?
