Why can't they keep chicken??? Chicken need water and layers pellets (which store fine). You get fresh eggs every day and free manure to use in your greenhouse! I really don't understand why they don't do it.
I think this would dramatically increase ventilation needs. How many people are on base? Remember, you're not even getting 1 egg per chicken per day. At that point, you're in the chicken farming business, not the science base business.
Also, how long would the chickens last with zero exposure to natural sunlight and cramped conditions? It could be hard on them.
