Chickie update: this morning my little peep had one eye open. Its standing up really tall, looking up and wobbly, not looking around, which I think is odd. Still not eating on its own (because it isn't looking for/at anything) but active and vocal. I think that a combination of its age and possibly blurry vision are preventing it from learning to eat. My hope is that it will continue to heal and start foraging when it can see. Is there something other than egg yolks that would be good force feeding emergency food?
