Macaw damage beak?

Hello everyone, my macaw has a damage beak from about a week. I know that it is still growing and they scrape it but I think that this damage is too big. Should I go to vet with him or it is normal?
I attached pic.
Thank you

That looks beyond the normal peeling. How is his diet?

I would take him to the vet to get it looked at.

We have him from november 2011 and he was used to eat mostly sunflower seeds. Now he's got a parrot food mix and we try to give him fruits and veg everyday but he do not rally like them. He eats only grapes and bananas, and cooked potatos mashed with carrot. From last week we give him some calcium and spirulina with a food.

Carrots are great for Vitamin A, which parrots need for healthy beaks. Instead of regular potatos I would try to feed him cooked sweet potatos, the orange veggies are really good for them.

It's possible that his older beak is just breaking away for a newer healthier beak but that looks a bit severe to me.

From the picture provided, it does not appear that your Macaw has a damaged beak. Green Wing Macaws are very hard on their beaks and love to chew on wood toys, when chewing, the really scratch up their beaks. this is normal. My Neleno's beak always flakes off, chips in some spots, even bruises sometimes. Their beak grows fast so don't worry about the appearance of their beak.
I am very concerned about his diet, this is more important. you must find a way to increase fresh fruit and veggies into his diet, even if you have to hind them in other foods. Like Parrot bread mix, mashed sweet potatos, mix in some almonds. I would also advise you to give your Macaw 1 hard boiled egg with the shell but remove the yoke, this is very good for their beak and feathers. i would give him 1 hard boiled egg 2-3 times per week. this is also good for when the Macaw molts.
I found out by playing with my Macaw, I would give an almond for treats and ask my Neleno to perform a task, when he did, i would reward him with the almond, then I would ask for another task, once he performed that task, i would give him a pea, he hates peas but since i made a game of it, he ate knowing that he did something that pleased me so therefore he was happy to eat the pea. Now peas are offered and i don't see them on the bottom of his cage like I used to. You can also hide other fruit and veggies inside a paper towel roll, bend both sides and make them work for the reward inside, place some almonds and some fruit or veggies they don't like, when they find them and open the roll get excited and say what a good bird they are and they will eat it to please you. best of luck Joe

My young male will be turning tomorrow and he plays and chews so hard that one time he peeled like 3 to 4 layers back on his lower mandible. I was worried at first but still decided to peel the loose ends off for him and eventually all grew back and he is fine. He is a voracious chewer and being young he isn't very worried about how it looks. The same went for his tail feathers he destroyed them while playing but since then the ones that were tore up have fallen out and a bunch of new ones have started coming in.

Thank you very much for all yours posts. His beak is getting much more better now
