Oh! So you have access to and study the only manual for life, the Bible? Good! Now apply it to your flock of chickens, my dear! When all is said and done and you've done your research, are set to implement some form of new husbandry, and you have little niggling worries...just apply faith in the Lord to the formula and pray that He watch your flock for you when you cannot.
I've done this for years and attribute all my success with chickens to the Lord. He leads me to good ideas, gives me the courage to implement them, provides me with good dogs for a help mate in my farming and watches over all of my animals when I sleep and when I am traveling. He even lets me make mistakes so that I can learn from them and provide better care and stewardship for other animals.
He even gives me wonderful people on a forum to whom I can talk and mull over the good ideas I want to try or to tell about the mistakes I have made! I love Him so!!!! He's a wonderful Father to me.
