Roosters or Hens

[KelC13]

Im new to chickens. I incubated 5 eggs in January with all 5 hatching February 4th. All are happy and healthy however with being so new to chickens I was wondering if I could get some help identifying whether these 3 are roosters or hens. If better pics are needed just let me know. Thanks everyone
