We are new chicken keepers in an urban setting. We have (had) two laying hens and two seven week pullets. We let them out mostly supervised in our backyard, but will occasionally be in and out of the house. Late this afternoon there was a commotion and a raccoon made off with one of the hens. We feel extremely guilty as I had seen one around a couple of weeks ago and got too lax leaving them unsupervised. At the same time it seems unfortunate that we can't leave them to range in our contained, urban backyard while we are in the house. Is that just the reality here? They love being out in the yard so much but I can't take losing any more! She was such a sweet girl and her hen pair is pretty upset. We ended up putting the two chicks into the main coop tonight as we were planning on soon anyway and we didn't want to leave the remaining hen alone. They are are cuddled up on the same roosting bar tonight.
