Our GP Emma is 7 months old and a "slobberer" when she catched one of the chickens outside of their encloser. At least once a week one of my chickens will decide they want to see whats on the otherside of their fence and comes out to wander around (6 ft. high fencing no less!)
Emma will catch them, lick and nuzzle them till they are just a pile of drool and matted feathers, then she'll bring them up to the porch door for me.
The poor things get a good warm bath, towel dryed and put in a box to dry off and fluff back out. They sleep forever after one of Emma's "treatments".
Emma has a "soft mouth" meaning she'll hold a bird in her mouth but not bite or crush them. Doesn't matter how big or small they are, she handles them the same. When chicks escape, you can't see them in her mouth cause she's got these droopy lips but you sure can hear them!
She is just the best farm dog and a great member of our family.
