Abnormalities that occur in eggs during formation

• Meat spots: a piece of tissue is torn off the ovary during ovulation. It comes down with the yolk resulting into a blood spot
• Blood spots: a drop of blood is shed off the ovary during ovulation and comes along with the yolk resulting into blood spot.
• Double yolk: two ova are shed at ago by the ovary later being enclosed in the same shell.
• Shell less eggs: nutritional imbalances and defects in the shell gland cause failure of the shell to be deposited on the egg during formation.
• Thin shell: disease and nutritional imbalances lead to the laying of eggs with thin shells.
• Deformed eggs: eggs with abnormal shapes due to defects in the isthmus where the shape of the egg is determined.
• Eggs with rough surface; uneven deposition of the shell on the egg leads to the formation of such eggs.
• Soft shelled eggs: failure of shell gland to deposit a hard shell due to inadequate calcium in the diet or other defects.
• Small sized eggs: these may be due to poor feeding or hormonal imbalances.
• Abnormal smell of the yolk; it may be due to diseases of poor feeds eaten.
