Automatically cooking the chickens is possible, but the timing would depend on how many chickens are in the egg pen, which would affect how often eggs are laid. A higher population would produce more chickens so the cycle would be shorter. That would just take some testing to find the optimal timing. I suppose after leaving the return gate open for a few hours to build up the population, you could close it and activate the cooking cycle (would that make it an egg timer??). I might show a future version with an optional timer, but for now to keep the build simple I just have it being activated manually.
