we have now lost 4 chickens. We make adjustments, and it happens again. the attacks are happening at night or dusk (right before they coop up). They chickens completely disappear with no trace except for a few feathers. It even grabbed a chicken right out of the coop right at dusk. we have been taking measures like making sure chickens are up early, ect. but last night I had the last straw. The animal RIPPED the sliding door off the track!! My brand new Buff Orp is missing. I am going to bolt some plywood over the hole until my hubs is back from his business trip and can make a new door. so here are my questions: what type of door for at my coop ramp since a sliding door isn't safe? do you think it is a racoon? we are going to try and trap & kill it...any tips?
