I was a bit confused bb’cause you replied to an old thread. If you start a new one next time you have a question. You probably get more responses.
x2. Though I normally don't like to respond to necroed threads this had potential disaster written all over it. Not to say that it's impossible to get good results - sometimes you can get lucky and things work out without any issue - but I definitely hoped the poster would consider cons along with the pros (getting more birds, helping friend) before committing to a situation that could perhaps could blow up in their face.
