Yes as others have said, that is a Very bad case. I occasionally have scissor-beaked Easter Egger chicks hatch out. By age 3 weeks, the chicks that are too severely cross-beaked to eat normally begin to noticeably lag in size and weight compared to their siblings. At this point i euthanize. (I feel sad even while typing what i just did, because it "isnt fair" an innocent little chick drew the short straw in life.) Unfortunately, the adage "life isnt fair" is very true.
As some have already posted here, yes it is possible to keep your chick alive with a massive effort on your part. You would need to tube'feed it multiple times daily, every single day for the rest of its life. If it were mine, i would say a prayer and humanely end its life. I dont make that statement lightly, because i give ALL my flock members a chance to live out a full normal life, treating them as needed along the way for conditions that can be healed and cured.
The decision is entirely up to you, and you've gotten good informative responses here on both sides of the spectrum.
