Since January 12, it has truly been deep winter. First came the snow; then it got cold – again temperatures were as low as -14/-15 C (5 -7 F) for several nights.
On January 26, the temperature was again above freezing, so I was able to check whether everything was in order. In one of the enclosures against the wall, the little heating lamp burned out one time (of course, it was late at night and bitterly cold), but it was noticed just in time – the snow was removed, the plastic-sheeted shelter opened, a new bulb screwed in – nothing had happened. The photos of all three locations show that everything is still OK.
