Brooding 200 Vanaraja Chicks Through December Power Cuts

The signs point to uneven temperature and poor air exchange, not a single hot or cold brooder.

• Huddling and shivering in a corner = chicks are cold at the periphery or in a draught. The edge reading of 24°C is too low for day-old chicks.
• Panting with wings out near the brooder = local overheating and/or poor ventilation. A reading of 39°C 30 cm from the source is not the same as the temperature at chick level; the source itself may be much hotter, and charcoal also consumes oxygen and produces carbon monoxide if the area is sealed.
• Damp litter around waterers and ammonia = water spillage plus inadequate ventilation. Wet litter chills chicks and increases disease risk.
• Pasted vent = often linked to chilling, dirty water or poor early feed/water intake.

Target temperature measured at chick level, about 5 cm above the litter, not 30 cm above it:

• Week 1: 33–35°C at the brooder edge.
• Week 2: 30–32°C.
• Week 3: 27–29°C.
• Week 4: 24–26°C, then withdraw heat if nights are warm.

The behaviour of the chicks is a better guide than one fixed thermometer. If they spread evenly and sleep with necks stretched, the temperature is right.

Space: a 3 m diameter guard gives about 7 m², roughly 0.035 m² per chick - acceptable for the first week. Expand the guard after 7–10 days. By 4 weeks allow about 0.09 m² per chick (about 18 m² for 200). Provide 2.5 cm of feeder space and 1.5–2 cm of water space per chick, and more waterers than four as they grow.

The 40 W bulb is not a serious heat source for 200 chicks; the charcoal brooder is doing the heating, but it is also the main risk if ventilation is poor.

Before each night

1. Check the brooder is working at least two hours before dark and that the guard is dry.
2. Keep a standby kerosene brooder or a second charcoal unit, with a flue or chimney to take fumes outside. Never seal the brooder room to keep heat in.
3. Fill hot-water bottles or sandbags, wrap them in cloth, and place them along the guard wall as a short-term heat bank during a cut.
4. Lower curtains on the windy side, but leave the ridge or top ventilation open. Use a temporary inner curtain to reduce the brooding area rather than blocking all fresh air.
5. Keep dry litter, spare bulbs, matches, a torch and a thermometer at the shed.

During a cut

• Reduce the brooding area with a temporary guard so the chicks can huddle near the heat, but do not crowd all 200 into a sealed box.
• Watch for chicks piling: piling can smother chicks even when the air is not cold.
• Do not bring a charcoal stove into a closed room. Carbon monoxide kills quietly and causes panting, weakness and deaths that can be mistaken for heat stress.

After the cut

• Recheck the temperature at chick level, remove wet litter, clean waterers and count dead birds. Record the mortality and the likely cause.
• If deaths continue after the brooder is corrected, call a veterinarian; do not keep adding glucose as a substitute for diagnosis.

Water

• Give clean water at about 20–22°C. For the first 4–6 hours after arrival, a 5% glucose solution with electrolytes is reasonable; after that, fresh clean water is better than持续 sugary water.
• Use shallow drinkers that chicks cannot drown in, and place them on a slight platform or wire mesh to reduce spillage. Clean and refill at least twice daily.
• Check that all chicks can reach water; a chick that is huddling in a corner may be dehydrated and cold rather than diseased.

Feed

• Use a chick mash of about 20–22% CP for the first 3 weeks. Provide feed little and often, and use chick feeders rather than broad troughs.
• A rough guide is 10–15 g per chick per day in the first week, rising with age; watch crop fill rather than relying only on a table. A full, soft crop in the evening is a good sign.
• Do not put feed on wet litter. Keep the feeder height at about the chick's back level and adjust as they grow.

Health and management

1. Clean the pasted vent gently with warm water and dry the chick; check whether other chicks have dirty vents.
2. Remove wet litter and add dry litter. Keep ammonia low; if your eyes sting, the chicks are breathing too much gas.
3. Confirm the hatchery did Marek's vaccination. Follow the local schedule for Ranikhet disease and infectious bursal disease; do not vaccinate sick or stressed chicks without advice.
4. Keep visitors out of the brooder room for the first two weeks, use dedicated footwear, and dispose of dead chicks away from the flock.
5. Record daily mortality, water intake, feed intake and brooder temperature. Twelve deaths by day 3 is above what good brooding should produce and needs a written cause, not guesswork.
