Hello, You can use chicken on champions that fullfill the following conditions :
1 star chicken to rank up a level 10 1 star champions
2 star chicken to rank up a level 20 2 star champions
3 star chicken to rank up a level 30 3 star champions
4 star chicken to rank up a level 40 4 star champions
5 star chicken to rank up a level 50 5 star champions
If you select a champion that fullfills these conditions in the tavern, the chicken that correspond to their rank and level should appear at the end of the champion list.
Hope it helps :)
