For NM, 4 mating cages were maintained each with 5 roosters and 45 laying hens. The other birds were reared in 3-layer complete ladder cages for AI, for which 180 hens were maintained in 60 cages with 3 hens/cage and 20 roosters in 20 cages. ...

Group 1 chicks served as intact control. Trimming of claw of group 2 chicks was performed by the method of partial amputation of the third toe (along the distal phalanx) at day of hatch; the first and third toes were declawed in the group 3, while the second and fourth ones were trimming in group 4.

Hatching success was up to 85% (range 75 to 85%) in different nests. The dense vegetation consisting of Dodonaea viscosa and Poa annua provided shelter, cover and abundant supply of insects to the chicks. The study concludes that the breeding season of Chukor partridge in Dir Lower ...
