Birds eye crispy chicken?

Got a box of 4 birds eye crispy chicken in the freezer thinking of having one tonight with a salad. Anyone know the syns of just one?
If I'm working it out as 20 cal = 1 syn it would mean one is 10.5 syns. However chicken is free so I really don't know...

Thanks in advance xxx

According to the website:

Crispy Chicken, frozen 4/6 pack, 85g each EE 7.5, O 7.5, G 10.5

Hope that helps?

Thankyou xxxx
