Bear with me, I am horribly sick with a Sinus Infection and cough and am just browsing through and saw this post.
I think to some extent you are right OP. In my first year raising chickens I lost 6 birds to injuries and predators.
I warn new chicken people all the time that unless they are willing to take their chickens to the vet to be put down, that things happen and that at some point, you will probably need to put one down.
I also tell anyone who has bought from me that if their chickens ever need to be culled, I will do it for them because I understand how hard it can be with a "pet" chicken.
After awhile you almost get used to it.
I do think that people need a strongish stomach to raise chickens. The amount of things that can crop up are endless it seems. I have a relative that couldn't even deal with picking up a cat hairball, let alone the idea of dealing with a chicken with worms or cocci. It would make him vomit. Someone like that shouldn't have chickens.
You're own beloved pet cat or dog could injure your free ranging backyard chicken in the blink of an eye, even if he/she has never shown agression to another living thing before, and the injury could be severe and leave the animal still alive, leaving you to cull it or stitch it up, or something.
If you cannot under any cirsumstances deal with:
Poop
Worms
Blood
Injuries
Administering medication
Force Feeding
Giving an injection
Performing sutures
Removing sutures
A prolapse (this is a big one to me, if you even have one hen then you need to know how to deal with this and then must be able to perform the following)
Killing the bird
Then I too don't feel that you should have them.
For me at the end of the day it comes down to making the bird suffer. Right here on BYC, I have seen people come on and be like "My bird is seriously hurt, But I just cannot bring myself to stitch her up, put her down (with half of her innards hanging out her rear), or I cannot open her mouth to give meds, etc."
It boils my blood. Suck it up and get it done already, you'd want someone to go through the trouble and care for you if you were hurt or sick.
I JUST sold two chicks to first timers about an hour ago who showed up at my farm unanounced (dontcha hate that?!) and had to explain to them that there are no vets in our area that will treat chickens and that any vet care is up to them or some other chicken savvy person.
They were concerned but then countered me with "Well you're the chicken lady, any problems and we'll call you!"
Fine by me. I like it that way.
I also told them to come join BYC
