so I gave up the battle of keeping the sparrows out of the coop my birds free rang in my back yard and only lay eggs in coop and sleep at night. my girls have 4 nesting boxes in there coop but only use 2 and the 3rd one once and while. my prob now is there have been 2 sparros i see in the coop all the time now i am catching them in the 4th nesting box and i think it looks like thats where they want to have there baby birds ( I could be wrong) my fear if I let them when the baby birds hatch or even when there eggs my girls will either take over the eggs and hatch the birds them selfs and of course those babys would die as they are not like chicks and can feed them selfs or when the eggs hatch my chicken will eat the new born babys. no of course I could always block off that nesting box so the chickens cant get in there and let the sparrows do there thing. Oh ya these sparros also hang out on the rost at night and sleep with the chickens some nights and the chickens dont seem to care. I dont know has anyone ever had this kind of a prob what do you recomend,
