That should work OK, bigger would be better, you'll have to see how they do with it.The distance from the red board to the inside of the front board is 2 1/4 ". What do you recommend?
Good, the extra piece is what will make the red line lower than the green line, so the trough is not as full and it's less likely for feed to be billed out.Tho the billing out is really hard to curb. I have played with a half dozen different feeders, most recent seems to be the best so far.I do have a piece that will fit down inside to decrease the flow of food. The red and green boards are at the same level, so i can adjust that too. Thanks for the pointers!
This was taken during the prototyping phase. Details here:
