We have been fighting the rat population between our barn and the neighbors barn. I want to move my chicks out of my garage to the coop soon, they are about 3-4 weeks old but am worried about the big furries hurting them. I have standards and silkies--so different sizes. Would they? I am looking into getting one of those Rat Zapper contraptions--they had a good review in one of the poultry mags. Anyone use one of these? Chicks can't get into one of these can they? I don't want to put bait down, cause the rats move it constantly and I have a 4-legged 800 lb dog (ok 2yr old horse) that I have to worry about eating everything! I swear those rats laugh at me when I check the coop at night and I can't reach the hoe fast enough to whack them! Furry Devils!!
