Laying Hens Learn to Avoid Feathers
Previous work demonstrated an association between feather pecking and feather eating in laying hens. This raised the question if digestive feedback affects feather eating or feather pecking in laying hens. We hypothesized that feathers enriched with sugar form a positive feedback and feathers enriched with quinine sulfate form a negative feedback ...

Aromatic plants, nest bacterial diversity, and nestling condition in Corsican blue tits
According to the ‘nest protection hypothesis', some passerines incorporate fresh aromatic plants into their nests which reduce pathogens that can negatively affect nestlings. We experimentally evaluated the effect of five aromatic plant species on the nest bacterial microbiota of Corsican blue tits Cyanistes caeruleus.

Magnesium Requirement of the Laying Hen ,
Abstract THE quantitative requirement for magnesium by laying hens has not been established. The National Research Council in 1966 listed the growing chicken's requirement as 500 mg. magnesium per kilogram of feed, but gave no estimate of the hen's requirement while Edwards et al. (1961) showed that the phosphorus level of the hen's diet had a marked
