we have the smaller/younger chickens in a chik-n-barn/yard combo. when setting the whole thing up i put 1/2 inch hardwire on the bottom of the barn and yard and also at the corners and other vulnerable areas. there are no gaps bigger than one inch. on saturday evening something managed to get a roo out of the coop! (he was my silkie/buttercup baby, only half grown!!!!). we looked everywhere for him on sunday but could only find some feathers in the yard. he is nowhere to be found. none of the other chickens are missing from that coop. the only way, i figure, that he could have been taken out of that enclosure is if something opened one of the top hatches on the chik-n-barn. but what type of predator has this capability? (besides humans . . .) i did buy a live trap on sunday in hopes that i could catch the villian and i've had it close to the coop for several nights but so far - nothing! this is like an X files episode!!!!! any ideas or theories are welcome.
