I live in an upper floor appartment in Germany and am barely managing the weather and I'm worried my birds are suffering in a similar way. The weather is only going to get worse the next days. Their behavior didnt change, they're just a bit more sleepy. I keep changing their water every couple hours, they are picky eaters so they're not interested in frozen food. Is there anything else I can do to make the weather more tolerable for them? Are they even affected or am I overthinking it?
