Multiple Choice

Laying hens infected with Salmonella enteritidis usually have significant disease including watery stool and decreased appetite.

Explanation:
Salmonella enteritidis in laying hens is usually subclinical. Many infected adult birds appear healthy and shed the organism, which is how eggs can become contaminated, even without obvious illness in the hens themselves. When disease does occur in layers, it is typically mild and often linked to stress or other concurrent problems rather than a severe, overt illness. Therefore, the statement that laying hens typically have significant disease with watery stools and decreased appetite is not accurate.
