Chicken Hatch With an Enlarged black eye :( What is this?

[AKendall18]

Hello Everyone,
I am very very new to this,
im wondering if anyone would be able to help me. I have had so far 11 chickens hatch and the 12th one just hatched about half an hour ago but one of its eyes its really really enlarged and completely black. The chick itself seems really health and is doing well. Im wondering if this is a birth defect? It is still in the incubator fluffing and drying out. Im not sure if i should add it to the folk if it might be a disease.
Thanks for your Help
Amanda

Yes, it is probably a birth defect. It probably isn't going to do anything to the other chicks.

Thank you for your reply. Ok that's good to hear. Do you think it will have trouble further along the track?
