Hi Becky, is this your first batch? I can see all that excitement replays in all of us during the phase of this hobby...can't help you with calcium injection or toxytocin, though, since we had no clues what that will do to the animals.
Call it global warming and Al Gore can jump all over us on this all he wants...but even one of our female which laid eggs like clockworks gave us dinged soft eggs this year...Bill Z called her's uncalcified and suspects there could be an infection somewhere but decided to keep it a secret to himself...so we thought maybe she's reaching that dying age like those of her league (in the ssp program) which happened recently, and since we're not doctors and nurses and know nothing about labour inducing techniques so we decide to let nature take it's course and provide whatever we could in our knowledge (more laying choices including man-made poop-shack with outdoor UVB lamps to compensate outdoor temp and extend day light cycle, also varying humidity levels in substrates...ect)...that was September.
Only until a few days ago; some six weeks later she dug a hole in the old spot and pops all in one go like she used to (no tell-tale-testing sites like many others of her specie that we've seen!) while her mates paces and waits on her side (yelp, we let them do their "normal" activities during all this time!) the clutch are getting bigger and if you count them dinged eggs together, it's about 3 times what a normal clutch would be...but again, her mate he's a hanky-panky-son-of-a-kamickazi
>>My cherry head tort laid an egg on tues. I took rads today, she has 3 more. She is still eating well. I also noticed that her eyes were a little runny/bubbly clear tears. ?When do I worry, should I intervene now or try to improve the environmental conditions first. ?I did add a tray of sphagnum moss in hopes that would be better for her to lay in(yesterday, but no interest). ?Today I moved her to a separate area, the whole thing is sphagnum moss I put an area that she can hide in as well. I also was going to try and raise the temp a little in case she is getting an upper resp. ?I have calcium injection and oxytocin, just not sure how soon I should resort to medical intervention. ?What else should I do and at what point would you intervene? ?Thanks.
