I have Nigerian Dwarfs but this will be my frist experience on breeding them. How do I know when the female is in heat? I do see her pee in front of him, he of course sniffs it curls his lips sometimes it just goes that far sometimes he chases her. I have them penned together since they have been actively calling to eachother this week. All other goats are separate. Now they are housed together at night. Where is my problem, don't know if they have breed or not. The other morning when I let them out her neck and shoulder was bruised. She was fine but bruised. Any suggestions.........
