No such thing as too many questions, no worries! The mare will probably want more space as she gets closer to foaling. She might not want the gelding around her as much, this is pretty normal. Stay in touch with your vet and a few experienced folks if you know of any near you, this is an exciting but yes, nervous time. Good luck and fingers crossed for all of you!

Sure there's right and wrong but mostly there's just a whole lotta different.
