Is there anything i can do to help it?
There does not seem to be any way to cure crossbeak, or to stop it getting worse.
Chicks with crossbeaks sometimes have other physical problems too (not obvious ones, but things that can prevent them growing properly or being healthy.)
You can make sure the chick gets enough to eat.
Tips I've read:
--Wet mash in a deep dish can help (chick starter + water)
--Extra time to eat can help (in a separate pen for mealtime, so no competing with other chicks to get the food)
--Tube feeding is required in some cases.
To know if it is getting enough food, you can weigh it and weigh a normal chick. If you weigh them each week and make a note of the weights, you can tell if the crossbeak is growing at a normal rate. If it grows much slower than the normal chick, either it needs more food, or it has some other problem (probably not fixable.)
If the chick sits around lethargic, it is probably not eating enough. If it is active and acts like a normal chicken, it might be eating enough. It is possible for a chick to eat enough that it acts normal, but not enough to grow properly, which is why I suggest weighing it regularly to check growth.
The chick will probably not be able to wear down the tip of the beak like normal chickens do, so it will get too long. You can trim it as needed, using a file or a dremel tool or a pair of nail clippers. Be careful not to trim the chick's tongue, and not to cut into the quick (part with nerves and blood in the middle of the beak.) The part at the end of the beak that is semi-transparent is typically safe to trim.
Some chicks with crossbeak go on to live fairly normal lives (with help for eating and beak trimming.) Some others do not. I cannot predict what will work for your chick.
Of course culling the chick is also a possibility. If the chick seems to have a good quality of life, and you are willing to provide extra care, there is no need to cull. But if you are not able to provide the care it needs, culling is kinder than letting it starve to death.
I also leave a liquid mash out for her at all times so I know she is eating enough.
