in multiple groups for larger numbers of hens. These are usually made of wood, and should measure approximately 30 cm on all sides, with a nest floor area of about 0.1 m 2.
�. Feed troughs should provide 10cm / bird or more. Hanging adjustable feeders are ideal for up to 20 birds / feeder. In both intensive and semi-intensive systems, laying hens need constant access to food and water, and feeders should be distributed evenly throughout the chicken house. In the semi intensive system, birds scavenge during the day, mostly for protein( from such sources as insects, worms and larva), minerals( from stones, grits and shells), and vitamins( from leafy greens, oil palm, and nuts), but energy supplements such as maize, sorghum and millet are important for higher productivity and should be given.
A good feeder should be:
Ω Durable enough to withstand frequent cleaning;
Ω Stable enough not to be knocked over;
Ω Of the correct height and depth;
Ω
Bird proof( such that birds cannot get into it or roost in it); and
Ω Equipped with a lip to prevent birds from spooning feed out onto the floor with their beaks.
