I have not posted in a while, but I am fairly new to this site and I posted in december about incubating and hatchling care. Well I hatched 20 eggs, 18 survived to become pullets. I moved 14 of them out of the green house ( where I raised them) into the seperated pen inside the coop. ( I lost 1 by now from introduction attempt). The first week was great until one night 9 were killed. I moved the remaining 5 in to the green house with 3 younger birds. Later I moved all 8 into a tortoise pen (that was vacant) outdoors until I fixed the damage in the coop. The tortoise pen is a 6x6 box for a desert species in the summer time. It had a wier bottom and lid. Some how a possum managed to lift the lid that was TIED DOWN and kill/eat 5 more birds. We got the opossum and thought that was the end. I moved the remaining 3 into a bird cage back inside the coop after I removed the divider. Once they were placed into the vacant bird cage another 2 were taken by a skunk.The last pullet was killled last night and I was just informed that 2 of the layers were just killed. Altho , when I left to investigate one was still alive, but missing half its face. After putting the still living hen out of its missery and tossing all 3 animals ( including skunk) out into the field next to the 5 pullets and opossum from days before I come to you for help. I wish to obtain more hens but I would like to have a better, planed out habitate before anything is decided upon. I have 2 remaining hens and 2 remaining roosters. ( one was bought as a pullet and was told it was a female). The remaining 4 birds were injuried as well but nothing serious. I am going to sepearte the roosters for now until something is decided. I thougth about removing all the chips, and putting down chicken wire then, once agian, cover back up with fresh shavings. I am not sure how this will do agianst preditors. although the wire on the tortoise pen to prevent burrowing out kept the opossum from digging in. Any advice on how to handle this situation would be greatly appreciated. And BTW, we would of saved the meat if it wasnt a skunk that did this. I can still taste the saturated air that filled the coop with the spray. I would like to build back up my flock( since I enjoy breeding chickens) but if my time is going to be wasted in myself continueously loseing chickens I dont see the point.
