I tried last week to bond two sisters back together afterbeing apart for 14 weeks. Im too scared as soon as they start chasing and nipping i stop the bond process. Any tips of whats 'normal' bonding behaviour and whats not. When i first put them together one female jumped on the other and starting 'humping' for a better word her sister. After halve an hour they started chasing and nipping but i got worried.
