I just build a new coop and recently had to take my chickens out of it and put them in their old cage because they tried to eat a staple aka Unail and Im looking for a magnet that is strong enough to pull an iron staple/Unail at least 2 to 3 feet away. That way I wont have any worries about 1 being left in there to try and eat. I had a huge roll magnet that is pretty strong I thought but it didn't pull the staple/unail if it was laying like 3 inches away and I think that's how I missed 1 possibly more. Anyway if you have a magnet in mind where I can get one. Please let me know asap thanks. GOD bless.
