The grey part is the humanoid root part, which is too low.
And every time I try to move it up/scale it it scales the chicken also which I don’t want. I don’t want it to be too low so that I can avoid the rigged mesh to seem like their floating, and even if I change the hip height it still doesnt work because the humanoid will be in ground if I make hip height lower and the chicken will be inside ground which I dont want.
