Hi Markus,
my english is also not very good, but when you visit this site regularly it's getting better and better, I can tell
We put our garters in HIBERNATION (<--that's what I've learned already
)in about 2 weeks, becouse the outside temperature was too high lately. The weatherforecast says it's going to be 19' c tomorrow !!
So now they don't get any food anymore. The adults get a hibernation of 2 months and the jung garters 1 month. I don't know if this is the best way, but it's working perfect for our snakes.
Hopefully we got next year babies of sirtalis sirtalis, s. sirtalis black, sirtalis tetrataenia, radix, proximus proximus, marcianus, elegans terestris. The others are not old enough yet.
