Moldy food poisons chickens and should never be fed to them. Premixed nutritionally-balanced food is available in bulk (e.g. 50 lbs), or you can make your own by mixing together chicken scratch (whole wheat & cracked corn sold in bulk at feed stores) and a good selection of wild bird food.
Updated March 03, 2016. The hepatitis B virus is transmitted when blood, semen or another bodily fluid from an infected person enters the body of another individual. Because the virus is extremely infectious - 50 to 100 times more so than HIV - even brief, direct contact could be enough to cause infection.
The hepatitis A virus is transmitted primarily by the faecal-oral route; that is when an uninfected person ingests food or water that has been contaminated with the faeces of an infected person. In families, this may happen though dirty hands when an infected person prepares food for family members.
