Hi I am planning on getting some chickens and I was wondering do buff Orpington and black jersey Giants do ok together due to their size and do the pick fights with each other?
Welcome to BYC -- it seems you may have stumbled into the wrong section for the information you are looking for as this has been posted in Ostrich, Emu and Rhea -- you might find you have better luck posing this question here: https://www.backyardchickens.com/f/2/managing-your-flock BYC is such a big place full of so much information it can be easy to get a bit turned around from time to time. When you have a moment, you may also want to stop by here: https://www.backyardchickens.com/f/44/new-member-introductions and introduce yourself to the community - we look forward to hearing more about you!
That said - *I* would not hesitate to mix those two breeds, nor would I anticipate issues based solely on the two breeds involved - but, as with any flock, you will have to watch of issues that may arise due to the difference in personality of individual birds within the group, regardless of the breed.
