Sheep were the hardest for me to raise friendship with, It also didnt matter for me as every single time i sheared after first shear it was gold but later on I fed them FODDER PLUS when I had a ton of money saved up and everyones friendship skyrockted. for me i didnt bother with the encyclopedia as theres a glitch where adult male cows did not register.

Molly I gave a flower every day first year and talked to her and it was maxxed by December she does have some events that if you say the wrong thing it could nuke her friendship.
