Want to reduce spillage of untrimmed laying hens?

Since the introduction of the ban on beak trimming, untrimmed laying hens have had more difficulty drinking from the drinking nipples. They tend to spill more, and their water intake can decrease. This can ultimately have a negative effect on the health and performance of the hen. But how can you prevent this?

Untrimmed laying hens drink differently than trimmed laying hens. In contrast to trimmed hens, untrimmed hens peck the nipple with a bent head. For this reason, they have to make more effort to drink water and ultimately spill more. As a result, some hens may not drink enough water and perform poorly. Monitoring water consumption can be a useful tool for determining whether the animals are drinking enough but, due to the spillage, these results may not be accurate and can ultimately mislead you. Walking through the house and observing the hens’ drinking behaviour with your own eyes is still one of the best ways to detect problems.


What to do in the event of excessive spillage

Here are several ways you can maintain the water intake of your untrimmed laying hens and reduce spillage.

 

1. The height of the drinking line

This can be an important point of attention, especially at the start of a new round. The height of the drinking line can be a problem for young, untrimmed laying hens. Because they turn their heads to peck at the nipple, they have to reach further, and when the line is too high they will spill more. Lowering the lines, if possible, or placing an elevation of some sort below the drinking line makes it easier for the hens to reach the nipple.

2. 360 degrees drinking nipples

Impex has conducted extensive research and concluded that a 360 degrees drinking nipple, such as the I-Flex 14-SP, is the ideal nipple for untrimmed laying hens and results in considerably less spillage. Thanks to the manoeuvrable pin, the hens do not necessarily have to approach the nipple with a straight neck from below to activate it. They can also approach it with a bend head, making it easier for them to drink the water. Moreover, because this nipple closes faster than a normal nipple, the spillage is also significantly reduced.

 

3. Drip cups

The use of drip cups reduces spillage, because the water the hens spill while drinking is collected in the cups. Hens who have difficulty drinking from the drinking nipples will gladly drink the...
