We have almost 4-week old chicks who were very scared of us at first and wanted nothing to do with us. Now, however, they fight over who gets to sit on your head/shoulder. When I bend over to wipe up poop (which I am constantly doing because we are battling cocci), they fly and perch precariously on my back. Here are my questions- 1. Should we allow them to do that? When they are full grown chickens they aren't going to be wanting to do that will they? 2. Why are they doing that? Is it to be in a higher spot? Even when I am hunched over cleaning and by far not the highest thing in the room, they still want to be on me. Thanks for any suggestions.
