Name the two phases in the life cycle of poultry.

Explanation

### Step-by-Step Solution:

1. **Identify the Life Cycle of Poultry**: The life cycle of poultry consists of different stages that birds go through from hatching to maturity.

2. **Define the Two Phases**: The two main phases in the life cycle of poultry are:
- **Grover Phase**: This is the period after brooding and before sexual maturity. During this phase, the birds grow and develop but do not lay eggs. This phase typically lasts from 9 to 18 weeks.
- **Layer Phase**: This phase begins with the onset of sexual maturity and continues until the end of the laying cycle. During this time, the birds are capable of laying eggs. This phase generally lasts from 18 to 72 weeks.

3. **Summarize the Information**: In summary, the two phases in the life cycle of poultry are:
- **Grover Phase (9 to 18 weeks)**: Growth period before sexual maturity.
- **Layer Phase (18 to 72 weeks)**: Egg-laying period after sexual maturity.

### Final Answer:
The two phases in the life cycle of poultry are the Grover Phase and the Layer Phase.
