Can you share a photo of the chickens? I had them too also during winter and never had any problem with what they look liked (except as I bought them).
With me they do not lay eggs during winter. It's too cold plus chickens need sunlight to do so. If it's too hot they do not lay eggs either.
It's the chicken's nature not to through the entire year. If you ask me chickens are better than pigeons. I have plenty of them overhere and they are a plague (and called the rats among the birds, they spread diseases).

Is there a balcony on your roof? Do the chickens have room enough or are they fighting each other?

No phones in the classroom is a good thing. There's a great world to discover if we aren't always check our phine.

I wish you a great time at college.
