Using excessive drugs in poultry farming can cause serious problems for both the birds and the farmers. It is important to understand the risks involved to maintain healthy and productive flocks.

Disadvantages:

1. Drug Resistance: Overusing medicines can lead to bacteria and parasites becoming resistant, making treatments less effective over time.

2. Health Risks to Birds: Excess drugs can harm the birds’ organs and reduce their natural immunity.

3. Residues in Eggs and Meat: Too many drugs may leave harmful residues in eggs and meat, which can affect consumers’ health.

4. Increased Costs: Buying and administering many drugs raises the overall cost of farming.

5. Environmental Pollution: Improper disposal of medicines and their residues can contaminate soil and water.

6. Regulatory Issues: Excessive drug use can lead to violations of food safety standards and result in penalties or loss of market access.

Farmers should use drugs responsibly, following veterinary advice and only when necessary, to protect their birds, consumers, and the environment.
