Chickens stuck in Fence Corners

This should be working as intended shouldn't it be? Because of the small hitboxes that chickens have, they often get caught in the corners. You cannot move them because your coordinates never can surpass that of the chickens, because of the bigger hitboxes of the player. You cannot breed them because the hitbox (note: not the physical barrier hitbox, but the outline hitbox) of a fence corner is in the way, so every time you try to right click the chicken, you end up rightclicking the fence corner. Hope this helps.
