You are using elimination to control rodents, the first steps are sanitation and exclusion. Elimination alone will not stop a rat infestation.
Sanitation is a treadle feeder, bulk feed in metal barrels, cleaning up pathways that rodents can use to travel without their natural predators seeing them and catching them. Do this first and you will eliminate the rodent problem for good.
Next step is exclusion, making the coop rat proof, expensive and difficult to accomplish. But like the sanitation it is a once time cost.
Poison and trapping never end and the colony wises up to the bait and traps, the rodents are still there drawing in other predators that also like to eat chickens, eggs, and chicks.
