Thanks for all that info - will put sponge in next time. The Humidity was apparently 65-70%, do you think the reading may be faulty or should/could it be even higher (I have an octogon advance 20 with manual humidity control)?
Spent 30 mins making 'Egg head poo bum the first' (as it is now called) a chicken wire sided cage to go in the box... others were curious but obiously couldnt get at her, next time I looked a few minutes later, egg head was out through the chicken wire and huddled in with rest (doh!!)!!! She has finally stopped peeping! Will keep close eye, but all seems well!
