We just got 4 beautiful 8 month old Rhode Island Reds and Partridge Rocks on Saturday (2 days ago)! They are settling in nicely (got our first egg after just one day!) and we're realizing that we have enough space to add 2 more. We are considering picking up 2 more from the same flock and the same farmer we just got them from. They would be the same 2 breeds, same age. Is there a need to go through a whole introductory period and quarantine since it's only been 2 days since they were together? Fast advice would be much appreciated since we'd prefer to get them today or tomorrow!
