I was eggifying some animals when i ran out of space on my inventory anjd i wanted to eggify some chickens. It said i didnt have space in my inventory so i threw some stuff out and eggified the chicken then move mon to a next one and it said i didnt have space in my inventory. Turns out u can't eggify an animal if u don't have space in ur inventory even if u already hav an egg of that type
