I just finished sending my guineas and rooster to Freezer Camp. I tried pithing my first guinea but it didn't work. Maybe their head structure is too different, Then I proceeded with slicing the jugular - that worked quite well and didn't really seem to upset them too much, had a really sharp knife. I tried scalding them, but when I pulled on the feathers the skin ripped, so I skinned it. Then I tried pulling out the feathers without scalding and the skin still ripped so I skinned all the guineas. After pithing did not work with the guinea, I didn't want to try it on my rooster (his name was Edmund), so I cut his jugular also and he went quickly. I scalded him and the feathers came out really nice and the skin stayed intact. I used a cone (large empty bottle of laundry detergent) for all of them. so glad it's all over. I do not enjoy ending their lives, but that's why I got them in the first place. I have them in the fridge for 3 days, then I'll move them into the freezer. Might have roast chicken on Sunday. Edmund was a good egg - until he attacked my puppy.
