Hello, there is someone offering 6 free birds on Craigslist. They said that they have slowed down laying, and I would like to check them out. Are there any thing I should beware of/questions I should be asking before I decide if their worth it? Any feedback would be much appreciated. Thanks. ALSO: stupid question, I know, but should I have them tested for anything i.e Pullorum. And how common is Pullorum?
