Try and not to upload with it the program, save it to your dektop. i record my videos from a TV(plug my laptop onto a TV) and i get 1080p. btw i use adobe element to edit and cantastia to record. IM not sure about the dying chicken bug, strange
I think what's happening is that since the babies have smaller hit-boxes now, when they grow up, they get stuck in the walls (if they're against a wall) and suffocate. I've been having the same problem with my cows.
I keep telling you people not to let your chickens try and cross the road so much. They could get hit by a minecart or something... -Sigh-
