That sure sounds easy. I think I used lemon juice to replace vinegar last year - happened to have a lot on hand. Looks like vinegar is better :) Thanks!
Wow, those colors are bright! Did you dye them yourself? And how? I did dye a few last year, but with varying success and certainly none as bright as yours..
And Happy Easter from me as well :)
My buttons do that when going broody. If you want to improve your chances of them actually going broody and staying so, I'd try to close off the opening of the log some more with branches, hay, grass or similar so they feel more sheltered and comfortable in there - and don't feel the need to run...
