Hi All just new to becoming a member but visited site often to find information on breeds and different things.My name is Kim and Iam from northwest Pa,mercer county,have had chickens in the past,buff orpingtons which I had to get rid of after having them from peeps until about 2yrs old!Neighbor didn't like the girls visiting every now and then,so so long girls,if only I would have built the coop and pen on the other side of the property!Now that I had been w/out chickens for a little over a year,I opted to build a run and anothercoop on the other side of my property and acquired 4 silver laced wyandotes and a jersey Giant rooster,and I mean Giant, really luv these birds.They are very docile,and luv people,however I just lost one last evening to a coyote or fox and it was heart breaking,I like to leave them free range all the time when I am at home and they will always go back into roost at sunset,and I close door to pen usually shortly afterwards,but one must have lingered a little to long out side of coop.Anyway Iam picking up 4 red orpingtons today after work,they are about same age 9-10 months,and wandring if anyone has any experience with introducing new birds into a already established flock? Any input would be great! Looking forward to chatting with fellow chicken owners! Thanks Kim. By the way Iam a guy not a girl,figured I would get that straight right away to avoid any missunderstadings!
