Thanks for the info. Not really what I wanted to hear, but he’s not as nice as when there were two so I get the social aspect.
If I get another bird do they accept each other quickly?
If I lend him to my neighbor (who has everything farm like) will I be able to get him back to me once he’s healed?
I really wasn’t expecting the attack from my dog so that will be dealt with.
Those are loaded questions!

- and neither ones that can be answered 100%, bc my experiences will be very different from someone else's.
Like I said (hmm..,I think I do?

), my boys love keets- so much so that they can be better parents than some hens. Others have males that will try or succeed in killing them. Hence, look no touch period.
If you add an adult- I'd still go with look no touch. A female adult would be more easily accepted. Males will fight for dominance. There are some that will tell you 2 isn't enough-and yet you had 2 who were perfectly content. If someone has an outcast female they want to rehome, she'd probably be happy, as long as he doesn't beat her up, too.(look, no touch. Now is a good season for acceptance though).
As for the dog, sadly most will tell you that once they get the taste for blood and guinea, it's a done deal. There are reports in the forum on this.
Mine are all shelties. One mothers them, one stays as far away from them as possible, and one isn't allowed outside when they are loose bc he wants to bite. That's easier to control in a small dog. And if you have small kids around, they might become fair game as well. If my grans are here & out playing, it's the same-mother, avoid, and locked up. Oh, and the son-in-law-the dog hates the son-in-law.
Will you get him back from the farmer?

. If the farmer doesn't keep him penned for atleast a month, the bird will attempt to return home.
Once he accepts the farm as home, you'd have to do the same if you took him back.
If the farmer has chickens, some chicken owners love guinea bc they guard the flock... But they will mate with a chicken, so depending on the farmer's frame of mind, he may love him or shoot him.
If you live in the country and want to keep your boy, *IMO* safe enclosure and keets are the way to go; inwhich case, welcome to the club!
