Apparatus and methods for treating the upper and lower beaks of poultry by noncontact heating of the upper and lower beaks of the bird are disclosed. The upper and lower beak treatment may include delivery of energy to the upper and lower beak in amounts sufficient to retard the growth and/or result in erosion of portions of both the upper beak and the lower beak. The energy incident on the lower beak may be reflected from a lower beak energy director (e.g. a reflector) or it may be provided a separate energy source.

Why it's free to use
- Filed January 14, 2004 and granted March 27, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 14, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 14, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
