Trying to make an automatic chicken feeder

Please know im not a coder i only have a really basic understanding of how code works

I can't tell if that means you want to code or not?

how to make it trigger the chickens breedable state

For creating the entity you can use;

AgeableEntity::createChild

Since you don't have much experience, this is an example if you have an instance;

		((AgeableEntity) entityIn).createChild((AgeableEntity) entityIn);

OPTIONAL:

You can check the entities age using;

AgeableEntity::getGrowingAge

Since you don't have much experience, this is an example if you have an instance;

		((AgeableEntity) entityIn).getGrowingAge()

Java lol. I don't believe this is possible in Mcreator, so if you want to do this you are going to have to code. If you get an error, though, post it and I will get back to you 🤗
