Hi all, this will be my first post on here, i've gathered a lot of good information already here, now it's time to join the forum and ask a question! First, Located in Central PA. 9 weeks ago i got my order from McMurray Hatchery. (Very pleased with them) All strait run, 5 Buff Orpington, 5 Rhode Island Red, 5 Silver Laced Wyandottes. They are obviously 9 weeks old now. They live in the back yard, in a coup i made out of a beat down old 10'x12' shed. (re-sided, repairs, etc.) So they other day, i tripped and fell in Tractor Supply, and somehow during the fall, acquired (to the best i can tell) 4 Barred Rocks, 4 White Leghorns, 4 Australorps, and 4 Black Sex Links. My wife is having a hard time believing how this happened, but that's another story. So i've got them in a raised re-purposed rabbit hutch, brooding in the coup. Added them in at night, next morning only a bit of curiosity, nothing major. So my question is about the integration. Most information i'm able to find, only involves grown birds mixing with chicks. The oldest birds in the coup are the previous mentioned 15. I'm assuming the process is the same as with adult birds? Less wait time being my existing flock is still quite young? Any input i can get is greatly appreciated, I'll try to add some photos when i get a chance. Likely tomorrow. Thanks!
