Twenty (20) helminth parasites were recorded with Ascaridia galli having the highest prevalence (73.4%), followed by Rallietina tetragona (64%), Rallietina cesticllius (56.3%), Davania proglottina (50%), Tetrameres Americana (46.8%), Rallietina echnioboitrida (35.9%), Choanotaenia influndibulum (32.80%), Capillaria cortorta (31.25%), Strongyloides avlum (31.25%), Hymenolepsis carioca (28.1%), Amoebotaenia cumeata (28.1%), Amoebotenia sphenoides (25%), Heterakis gallinarum (21.8%), symhimentus sp. (15.6%), Fimbriaria sp. (15.6%), syngamus trachea (12.5%), Trichinella sp. (9.37%),Capillaria annulata (7.8%), and Dispharynt spiralis (4.68%).
