We had a beautiful hen lose a toe. She was pecking at it & it looked very painful. I really didn't think she'd recover since it was looking swollen, so I decided to call up a friend for help culling the bird. We also had our 1st old hen who developed a shell gland issue. (Eggs constantly breaking in the nest & encouraging the others to eat eggs.) I had to trap her & force her eat treats with hidden calcium in them to get a normal egg. Then of course they went brittle again. It was time to cull her, but I was dragging my feet. Since the other hen was in pain, I decided to do both at once.
My friend did most of the work & I assisted. He suggested skinning to save time. (We sent the kids to the park. The kids knew the hens were being killed to end their suffering, but I just couldn't tell them that they were also going to be a meal.) We got through the dirty work & cleaned up quickly. The older one went into a marinade pot in the fridge & the other went into the freezer. I marinaded for 24 hrs, then it took about 12 hrs in the slow cooker for the tough meat to become tender. Is this normal? Because it took so long, we had pizza instead & will reheat the chicken for dinner today. We killed the chickens on Tues & had a chicken in the slow cooker on Wed, but they never questioned it.
As far as the emotions, I detached & just got through it. Now I'm feeling more guilty. I logically know that I took very good care of them & they lived good lives. I know the end was quick & I'm simply not wasting what we have been given. The emotions are still there. I am in no way a vegetarian, but I just feel bad. Hard to reconcile the conflicts.

Not unusual at all, you did what needed done but it doesn't negate the fact that you had cared for, and cared about, these birds since hatch....it isn't easy, but it is just a fact of animal raising....and you have done a great job in recognizing that their time had come and you needed to make the hard choices.
