Hello as stated im new to chickens, I am single stay/work at home dad of twin 3yr olds. Very happy to get our first chicks (already on ALL ORGANIC starter and want to have HEALTHY eggs for my TWINS! 2 welsummers 1 buff orphington (in picks has black spot on head from breeder for identification) MY WORRIES AND QUESTIONS... I have read as many of these articles as possible and STILL have a few concerns I hope to have them free range A LOT, I have already built a coop and run... NOW THE CONSERN THANKS FOR ANY IMPUT OR HELP I live in the city and have 6ft high wood fence between neighbors, ALL THE NEIGHBORS are friends and WILL NOT mind if a hen comes over during day. MAIN WORRY IS THAT ONE NEIGHBOR HAS DOGS?????? I understand my birds are large breed but from what I have read they still can get over 6ft fence no problem....WILL THE BIRDS BE "SMART ENOUGH TO AVOID THAT YARD?" I have considered putting mesh or something over ENTIRE yard but don't want to $ for that PLUS what if birds got caught up in netting???? AGAIN THANKS FOR READ AND ANY TIPS OR INFO YOU HAVE. .
