I've had issues with rats since getting chickens 1.5 years ago. We are even supposed to be part of an animal planet show regarding rats in the 5 boroughs, they say our segment (filmed over the course of about 3 months) might air in March. The exterminators from the show were never able to catch a rat. They put out like 25 traps but alas didn't get any. The rats did seem to go away for awhile but now they are back. I had an exterminator come to treat my house for a flea problem we have been having as well. He recommended we use poison inside the trap for the rats and assured me the hens could not get to it. Well, this morning, when I went to clean, feed and water, I see one of the traps moved from it's location. To my horror, I see the poison is now sitting at the entrance of the hole and is accessible to the hens. I assume they pecked at it last night before they went in for the night. There were no chunks missing from the poison, only small bits that seemed not to be eaten. There were crumbs lying on the bottom of the trap. All look ok and fine this morning, what do you all think? Will they be ok? I have an email in to my friend who is a vet and I'm waiting on her reply. Edited to add: the show exterminators never used poison because I was so hesitant to use it, they only used baited snap traps.
