Could use your advice! I have a flock of 7, including 2 roosters. My neighbor across the street also has a backyard flock, and has asked to "borrow" one of my roosters for breeding purposes with his hens, hoping to increase the size of his flock. I told him I'd be happy to oblige, (especially because he puts up with the pre-dawn noise these roos make) but have several questions since pondering it a bit more...
1) How will that affect the pecking order of my flock if one of the roosters are removed for a period of time, then reintroduced?
2) What about disease/illness? I've heard that perfectly healthy flocks can carry things that will make another flock sick. My neighbors chickens free range and come visit mine while they are in their run through the wire frequently. Will this make them less of a threat?
3) Anything else I should know about this? My ladies will likely be happy to have a slight reprieve from two very amorous roosters constantly breeding with them...
Anyone have any experience in this area? Would love to hear from you! (Also, I'd love to hatch some chicks this coming Spring, so any breeding insights you can offer would be wonderful!)
Thank you!!!
The owners that are irresponsible 
Let the roam or worst yet abandon them. These people I can hate with out restraint. It is bad enough when accidents happen when an animal escapes, but that is usually not the case.
