I have a set of 4 chicks that are about 5-6 days old. I got up this morning and one of the chicks was laying down and not moving. It isn't dead but it is definitely not well. If I pick it up it will give some weak peeps and open its eyes but then resumes laying down and closing its eyes. I checked its butt for pasty butt but it looks clean. Is it possible for it to survive? I don't want to prolong its suffering if it is just going to die. I don't WANT to cull it but I will. Thoughts? And if I do need to cull it what is the best and quickest way? Thanks.
