Hi I wonder if anyone can tell me how to stop rats operating the treadle feeder I have for my chickens. It is supposed to be rodent proof and so I was sure that all would be fine. It is mettle and the chicken has to step on the foot plate to open the feeder to eat, it then closes again when they step off. A week ago however I saw that rats are standing on the foot plate to make it go down while the others eat the food! I am freaking out. I have put down traps and poison (not where the chickens can get to it of course) but nothing seems to be working. I have moved all food supplies in side the house so there is nothing for them to eat outside. I have since been feeding my chickens twice a day from a bowl. I wait until they have eaten and look uninterested then take it away. Now I'm worried they are hungry? can anyone help with both these issues please...... thank you so much for your time.
