Chicken Questions: Isa Brown Hens. The one breed of chicken I receive the most questions about is the Isa Brown. They are the most family friendly of the all the chicken breeds and one of the most common throughout Australian suburban backyards.o make ISA Brown chicks they need to be bred from the pure bred rooster and hen.

How soon after exposure would symptoms develop? Symptoms generally begin 12-36 hours after eating contaminated food, but may occur as early as a few hours and as late as 10 days. Symptoms of botulism in infants may occur up to 14 days later. No, this cannot be spread from person to person. The symptoms of botulism make hospitalization necessary.
Botulism is a rare but serious illness caused by a toxin that affects the nervous system and can cause paralysis. The bacterium Clostridium botulinum, which is found commonly in nature, produces this toxin. There are several types of botulism, including foodborne botulism, which is caused by eating foods that contain the botulinum toxin. Botulism is a serious illness that should be treated as a medical emergency. Severe cases of botulism can lead to paralysis of the breathing muscles, respiratory or heart failure and death. If not diagnosed and treated, death from respiratory failure can occur within 1 to 10 days.
