Disadvantages of Free range system

 Eggs are difficult to collect or may be lost easily

 Bird security: Birds can easily be eaten by predators or

stolen.

 It’s difficult to control pests and diseases especially from

other animals outside the farm

 Record keeping of individual birds is difficult

 Birds can easily stray and destroy people’s crops

 Hygiene: Birds litter droppings everywhere

 Free range requires more space/land unless a small num-

ber is managed.

2. Deep litter System

In this system birds are kept and fed indoors.

The floor of the deep litter house is covered with litter from

saw dust, wood shavings, coffee husks, and crushed maize

cobs to prevent dampness in the room.

This litter helps to absorb moisture from the droppings of

the birds to keep the house dry and warm.

Advantages of Deep litter system

 Many birds can be kept in a small house.

 Birds are protected from thieves and predators.

 Bird droppings mixed the litter are collected and make

good fertilizers.
