Hey guys, I recently became a new chicken mom to 2 black Australorps (12 days old), 1 Sapphire Gem (9 days old) , and and Americana (9 days old). One of my good friends is trying to live vicariously through me, and would like to gift me a silkie tomorrow Is it possible to add to my flock at this point, and put her in the brooder with the rest? I need to aquire more information as to where she is getting this baby chick from. Do I need to worry about disease if it's not from a breeder? My girls are already getting a bit crazy, and I know there is a limited amount of time to add baby chicks to the flock, but would definitely like to bring this girl home if possible.
