Has anyone used the peck o matic feeder (see 1st pic)? I'm being over run with wild birds eating my chickens feed. Not only are they possibly/probably bringing in disease but I'm going through 50lbs in 2 weeks with only 8 chickens! I purchased the automatic feeder (see 2nd pic) last year but they were afraid of the open/close action & never used it. Don't want to waist $$ if it's no good.
