What do you do with that many chickens?I use to have a squirrel problem here..
I changed to a feeder about 16 inches in the air with small holes so the birds could not drop grain on the ground and the bushy tails could not get in..
Then I got a nasty predator and all the squirrels and about 200 chickens just vanished....
So it could be worse than just squirrels~! I wish I had the squirrels back now.
