hi so i am making a penguin but when i try and make the baby it doesnt work and just shows up as an adult.

here is the model class:

package com.relaxingleg.randomthingsmod.client.models;

The entity class:

public class PenguinEntity extends AnimalEntity {

    private static final Ingredient TEMPTATION_ITEMS = Ingredient.fromItems(Items.COD, Items.SALMON, Items.TROPICAL_FISH, Items.COOKED_COD, Items.COOKED_SALMON);

    public PenguinEntity(EntityType<? extends AnimalEntity> type, World worldIn) {
        super(type, worldIn);
    }

    @Override
    public AgeableEntity createChild(AgeableEntity ageableEntity) {
        return ModEntityTypes.PENGUIN.get().create(this.world);
    }

    @Override
    protected void registerGoals() {
        super.registerGoals();
        this.goalSelector.addGoal(0, new BreedGoal(this, 1d));
        this.goalSelector.addGoal(1, new TemptGoal(this, 1.1d, TEMPTATION_ITEMS, false));
