thanks for the suggestions
up until baby was born, we had no problems handling mom. She came to us with no problem, stood for grooming, etc. my daughter and I have spent hours with mom prior to her giving birth hoping that she would trust us enough to handle the baby. I will give her a couple of weeks to calm down, but if still not responding to us again within that time period, we may have to try something different. I really do not want to have to seperate them to handle the baby, but may have to by putting mom in the stall. There are no other horses around. She is in a pasture with baby. We got hold of mom today by bribing her with feed, but she broke lose as soon as my husband got hold to the baby. She has never tried to bite us before, but now she does try to bite anyone that reaches toward her as well as the ears being pinned and lunging. Vet has checked both and says both are healthy, gave both a tetanus shot. We had penned up mom and baby for when he got there we wouldn't have to try to catch them. I really do not want mom to become distrustful of us, but also do not want her to think that this behaviour can continue. I appreciate all and any suggestions. Thank you.
