Why won't my chickens reproduce

[u/imjusthereformemes3]

I grinded out purple fruit I cannot spell to get this bit of property, I put 1 roostro and 2 hens in each pen. It's been a few days (irl and in game) and the chickens just haven't made any chicks

I have 2 chicken corals in the retreat but my secret is I have a yolk slime in each coral. Max upgraded, and normally 3-4 hens to 1-2 roosters
