Is it ethical to euthanize this chick?

I have no experience here. How's the chick acting? Are the others pecking at the exposed area? I imagine the main thing is going to be keeping the area cleaned to ward off infection. Let's tag some of the hatching experts

I'd probably try to keep it as long as it's acting well but I am a total softie. Maybe put it in a small box or cup so it's still upright in the normal position but couldn't move around so much keeping it from closing. I'm curious to see what folks say. I wish you the best

I would cull it.

Poor chick, I don't know. It might just be a decision you have to make, since you're there in front of the chick. I personally would probably give it a couple more days, unless it is in obvious pain before then.
Keep us posted, I wish you the best of luck with him.

It is likely omphalitis (mushy chick disease, ) from an infection of the navel before or after hatch. Most chicks die within day or 2 weeks, and the ones that survive may be stunted and unthrifty, and prone to infections. I would cull it. Here is some reading about the condition:
