My girls have full access to our yard & coop all day, and are closed up in the coop at night. Problem is feeding - I keep water in & out of the coop, and the feeder inside. So that means I have to keep the door open in order for them to have access to their food during the day, which also lets in every !&*$* pigeon and bird in the neighborhood! I hate to close the coop up during the day and the girls seem to not want to eat at night (they just go in and go right to sleep). Am I worrying too much (they'll surely eat at night if they're hungry, right?)? These uninvited dinner guests are eating me out of coop and run! help!
