This study was conducted in Quezon Province, which not only determined the productivity and profitability of native chicken raising but focused also on the effect of the type of rearing system on its productivity and the factors affecting the presence of marketable surplus (MS) to mainstream this activity as an additional source of cash income. Results of the logistic regression revealed that the quantity of output produced, and medicines used increases the probability of having MS, but the quantity of palay, coconut and commercial feeds decreases the probability of having MS of growers and roosters. Whereas, the quantity of corn fed also decreases the probability of having MS of growers and hens. Female raisers usually have MS of these types of chicken. Meanwhile, the higher the age, the higher the probability of having a surplus of growers, while the higher the mortality rate the lower the probability of having MS of roosters. Lastly, adopting the free-range rearing system increases the probability of having MS of growers but decreases the probability of having a surplus of roosters. On the other hand, results of the stochastic production frontier revealed that there is technical inefficiency in chick and rooster production. The number of starting chicks is positively related to production of chicks, growers, hens and roosters. The quantity of palay or commercial feeds given to roosters has a positive effect on its production. Whereas, the amount of corn used for growers has also a positive relationship with its production. Amount of medicines positively affected chick production. Lastly, increasing labor used for raising hens or roosters would increase its production. The TE model for chicks and roosters revealed that adoption of freerange rearing system had higher TE, as well as with higher and positive net and adjusted net income. Provision of different support services for production was recommended.
