Maisie and Lily have restarted the morning grooming ritual. They do this almost every morning, spring, summer and fall; they even do it before starting to graze when we're out on pasture. They do the mutual grooming thing from neck to tail, sometimes for 15 or 20 minutes, switching sides from time to time. The white hair was flying this morning from Lily, who is shedding heavily. It continues until Lily signals Maisie to leave, sometimes by pinning her ears and sometimes by nipping Maisie on the side. Maisie also grooms with the other mares - she seems to be everyone's preferred grooming partner, perhaps because she does a good job without using her teeth too hard or nipping.
It's interesting that it's almost always mares who do the grooming thing. We've had geldings do it, but nowhere near as often and certainly not regularly. Similarly, the "face tag" (our horses don't wear halters in turnout so they can't do "halter tag" which is a variant) and play fighting - rearing, pawing - are exclusively gelding games - probably based on stallion behavior.
We're supposed to get more rain tonight, but right now it is good.
