Thanks for all that!I think it is more a process of elimination that actual checking for them. But may e the vet can ultrasound them a d tell? I dunno. I have not had to deal with it so not done much research on it. Kinda of... if a doe has quick cycles, not settling, not overweight, proper feed and mineral regime... stuff like that.... then you try the process to clear it up and see if it works.
But if she is not hunching then he is not hitting the x marks the right spot i would wonder about too.
Eta.... ooooo... have you tried giving BoSe? Maybe she needs a boost of selenium? Selenium def can cause fertility issues in both bucks and does.
They both should be ok for Selenium, as they have been on Replamin for a few months every week.
I will have the vet out next month, have him take blood for a test, and have a conversation about possible cysts.
