Managing Flow Rates
DRINKER HEIGHT
- Day olds start with the bottom of nipple at eye level (side action)
- Increase the height in relation to the chicks steadily over the first week
- Working towards vertical action
- Most common error – Too Low!
- Birds should be reaching up to drink (but not on tip-toes)
COLUMN HEIGHT
- Day olds start with approx. 10 cm from bottom of drinker pipe
- Increase as the birds grow
- Use cups and water consumption as a guide
- Remember: Higher flow achieved with vertical action not side action.
- Not enough water can lead to as much spillage as too much.
- The “sweet spot” changes daily.

70 to 100 ml / min (2.37 to 3.38 fl oz/ min)
|
HIGH FLOW NIPPLES
- Great for older, bigger birds
- Lower number of drinking stations required: up to 14 birds/nipple
- Wastage potentially higher
- Difficult to manage in early growth
- Podo bonuses make this less attractive

MEDIUM FLOW NIPPLES
- Suitable flow rate achievable for all ages
- Realistic number of drinking stations required: 10 birds/nipple
- Wastage is minimal
- Easy management throughout the crop
REDUCED FLOW NIPPLES
- Suitable flow rate achievable for all ages
- Realistic number of drinking stations required: 10 birds/nipple
- Wastage is minimal
- Easy management throughout the crop
