I bought this 8 month old colt out of the pasture. This is the first time she has been away from the mare and the first time in a stall. I finally got a halter on her but now she will try to paw you when you approach her. I think over time she will get out of that. She will come to you and nibble feed out of your hand, so I think she will be ok. What would be the best feed to start with? I have some 9% sweet feed in the stable but she just nibbles at it. I keep hay in the stable at all times. When would be the best time to deworm the colt- now or wait a while?
