Hi I am about to get my first 3 chickens and I just wondered if anyone could answer a few questions for me: 1> Can mixed chicken breeds live in harmony together ??? 2> If I put a fertile chicken egg of one breed under one of my chickens of another breed when it hatched would they treat it as one of their own ??? 3> Is wing clipping as easy as it looks ? Thanks for your time any answers would be appreciated.
