4(di)

1. Increased water consumption: Chicks may drink more water to keep themselves hydrated and regulate their body temperature in response to excessive heat.

2. Panting or open-mouth breathing: Chicks may exhibit panting or open-mouth breathing as a way to dissipate excess heat and cool their bodies.

(4dii):

1. Huddling: Chicks may gather closely together, huddle, and seek warmth from each other to compensate for the lack of sufficient heat from the electric bulb.

2. Reduced activity: Chicks may become less active and move less in an attempt to conserve their body heat.

(4e)

Advantages of using a charcoal pot in a poultry house:

1. Heat regulation: Charcoal pots can provide a consistent and controlled source of heat, helping to maintain an optimal temperature in the poultry house.

2. Improved air quality: Charcoal has the ability to absorb odors and gases, acting as a natural air purifier.

3. Reduced humidity: Charcoal has a drying effect, which can help lower the humidity level in the poultry house.
