I guess I am not normal or human. I could butcher my dog without second thought if need be. I respect and love him as a pet, companion and friend. Same goes for the chickens, cows and even the horses when we owned them. They are animals, I am human and above them on the food chain. Could I walk up to an elephant and shoot him in the head, sure. Not really an issue, would I, not unless I needed food. Shooting a deer, elk, elk, squirrel, fish,rabbit, etc. is very much the same Killing an animal is not a sin, not inhumane, not evil, not wrong, not disrespectful, etc. The main problem is so many people do not HAVE to kill their food anymore to eat. THAT is the problem, not those of us who take the time to do it ourselves, properly. Animals kill animals all the time, and sometimes for no reason at all. I suppose they are not normal humans either. Guess I'm out of luck. Anybody out there know where an abnormal non-human can get a beer???
As for good advise for raising chickens... Raise them 'dirty' and cold, don't use bleach, don't use medicated feed, let their water set for a while before you change it, and for us deep litter and chicken nipples have been an absolute blessing, and would never hesitate to recommend their use.
