Math ace - they have been together 4 months now. And when we got them we were told that yes they were wormed. We have not had any health issues with them and have been lucky they are healthy.
Kano - I understand the EE's are young, but the RIR are the ones I'm questioning. They are the ones that have stopped. I don't know how old they are exactly, all we were told when we got them was a few years old. The people we got them from didn't know. And if they were "too old" wouldn't the production gradually go down to nothing? Instead of all at once?
