I'm having a problem with wild birds eating my feed. I have aviary netting over the top of my chicken yard and fencing but they still are getting through it. I don't mind a few, but I'm talking about hundreds! So I'm offering feed in the morning for 1 1/2 hrs and evening for 2 hours - is that ok? It is 110 in the day here, I heard it is better to ease up on feed anyway in extreme temps, true? I have 8 free range chickens in a 25ft X 20ft area. Thanks!
