Help! Guinea keets cheek sunken in??

[NikkiRenee]

I noticed approximately a week ago that my Guinea keet has one cheek that is sunken in. it also looks a little discolored but the other cheek does not look like this. It was raised with another keat and 4 chickens and nobody else shows any signs of this issue. The Keating question is also larger than the other eating drinking and doing all the things that should be doing. Has anyone seen this or know what could be going on. I already Contacted the hatchery where I purchased it from and they claimed it looked totally normal

You know I never noticed the cheeks on mine, as long as it's eating well and feels like a good weight as compared to others I wouldn't worry, beautiful guineas!
