Active baby chick with eyes close

[Zamama]

Hi . I have 4 polish chicks one of them is closing his eyes but when i take him out of the cage he started jumping fof the cage as if he wants to get in and it seems that he is perfectly fine. But as i put him in the cage he again closes his eyes. Can any one help me finding what is the problem with him

How old is he hun? Normal for young chicks to be sleepy standing up

He is a 2 week chick but as compared to other he is closing his eyes more and not eating perfectly
