Kenbro is a dual-purpose breed which lays more eggs and its high rate of growth is higher than the ordinary Kienyeji (indigenous) chicken, the size of the eggs are much bigger compared to the Kienyeji. Therefore with proper feeding they can attain 4kgs or for the hens they can start laying at five and a half months.
They are also hardy just like the Kienyeji; they can scavenge for food and are more disease resistance.
Just like any other chicken Kenbro do moult for five or six weeks, therefore you should expect them to stop laying for the duration in a year. They use this period to relax and for the eggs to start forming again.
If you are planning to keep Kenbro or any other breed for fertile eggs to hatch you need to make sure you source the cockerels from other farmers who have pure breeds to prevent incest in your flock.
The only disadvantage of Kenbro is that they are heavy feeders compared to kienyeji, Kuroiler and KARI, and just like Kuroilers they do not go broody, therefore even when they are moulting they do not sit on their eggs.
The above can be covered by either having them as free rage so that they can roam outside and scavenge foe their own food or you can have Sukuma wiki, other greens and leftovers as supplements to the feeds to reduce the feeds cost
You can also use other indigenous chicken to sit on the eggs or use an incubator to hatch the eggs laid by your Kenbro birds.
