Initial studies have been conducted to study the properties of calcium carbonate (CaCO 3 ) from a wide range of poultry such as domestic chicken eggshell, Chicken Broiler egg shell, duck egg shell and quail egg shell. This initial study was conducted to determine whether the initial identification of a wide variety of egg shells of various kinds of birds contains Calcium Carbonate, knowing the nature of the initially formed crystals covering the structure, the study of crystal system, lattice parameters, space group and diffraction field. Proving the existence of Calcium Carbonate by FTIR is to understand the formation of calcium carbonate absorption band. Preliminary results from the nature of Calcium Carbonate wide variety of birds by using x-ray diffraction and analysis on chi 1.2 GSAS program, is for every eggshell which are Domestic Chicken, Chicken Broiler, duck and quail have almost the same initial properties of the crystal structure of CaCO 3 with a system formed rhombohedra crystals with lattice constant values a = b = 3.516 , 3.500 , 3.522 , 3.519 and 3.505 and c = 12.180 , 12.125 , 12.127 , 12.199 , 12.190 and 12.142 , R 3 C space group and orientation of the diffraction planes hkl in (2) 34,325, 34,110, 34,135 and 54,275. Further evidence was obtained by using FTIR absorption band that calcium carbonate (CaCO 3 ) in the sample eggshell, chicken eggshell, duck eggs, quail eggs and much more is formed on the Ca-CO group at wave number 1405 cm -1 , 873 cm -1 and 712 cm -1 .
