I have a chick that is missing his top beak and cannot stand. I need to cull him, I tried the vinegar/baking soda in a sealed container, was supposed to do the trick in 1 minute, I left him 20 minutes then took him out. I have put him in a ziplock bag, squeezed as much air out as possible, thought it would last 10minutes, so far it's been an hour and a half. If this little guy could stand I give him a chance but he just wont die! I really don't want to snap the neck, I'm afraid of the feeling in my hands something that I can't forget. Help!!
