Sunday last we held a blessing for the new chickens that arrived the previous week. The prayer comes from the Priests Service Book and is attributed to St. Modestos. It is a generic prayer for animals so I tailored it to fit for the Chickens.
O Lord Jesus Christ our God, compassionate and all-good, who fashioned in wisdom both the invisible and the visible creation; who pour your mercies upon everything that has been made by you; who, in your loving providence, provide for all your creatures, from the first to the last; hear my prayer and drive away and banish every injury and illness from all these *chickens* which are being used for the livelihood of your servants.Yes, Lord, look down from your holy dwelling place and bless all these animals, as you blessed the flocks of Abraham, Isaac, and Jacob, and all your faithful servants. Multiply them, grant them health, strength and productivity; render them robust and successful in the various services which they render. So that their owners, having derived abundant benefits from them, may engage in all good works which are pleasing to you, and may glorify on earth your holy name, of the Father and of the Son and of the Holy Spirit. Amen.
