11 Tips for Keeping Healthy, Stress-Free Chickens
Vaccinate your chickens.
Preventing problems is always better than trying to fix them. When you purchase baby chicks, you’re often offered the opportunity to have them vaccinated for a small additional fee. Vaccines can be given at various life stages of chickens.
Vaccines can be given by mouth, in the eyes, in the nose, or by injection, depending on the disease they are meant to prevent. Some vaccines prevent disease in one dose; others require several doses.
