This is my first post so here goes....I found a rat in the hen-house and immediately bought a 'snap trap ' and was unable to catch the rat w/the trap [although he ate the peanut butter off with out snapping the trap]the hens and boss the rooster freaked out two nights in a row when they saw rat. [3am I have a night lite for them. I was worried about the hens getting bitten by rat. BUT I am not worried now rat was found dead the next day with a blow to the head!!ONLY SIGN OF HIT WAS A SPOT ON RAT'S NOSE .CLEAN HIT AND THEY DIDN'T TRY TO EAT HIM, WHICH WAS MY OTHER WORRY.! thought this might be a concern for other s. I'll be forever grateful if this helps one person not go through what worry I went through for 2 weeks. 'I also had feral cats and dogs stalking my chickens when they were roaming my fenced yard, Solution...I bought a Beebe pistol and they ran at the sound of my missed shots headed their way. no one got hurt just scared off.!!
