Karen and Dan were moving a batch of pullets from the brooder house onto the pasture one evening, and saw three rats scurrying around. You know what that means: if you see three in the open, there must be thirty in hiding somewhere!
We usually don’t have much trouble with rats on the pasture. Our chicken feed is in big galvanized range feeders outdoors, and we move the feeders each time we refill them. Any rats who take up residence in tunnels under the feeders have their tunnels exposed when the feeders are moved. Something — probably owls — takes care of the rest.
