My DH, in a haste, before deploying to Iraq built a coop and fenced in a chicken yard around it for the 6 hens we acquired. I have 3 red sex links and 3 buff orpingtons. We learned right away that the sex links needed their wings clipped but the buffs never got over the fence I guess because they are bigger. We have 4' chicken wire for the fence. Well today, I found all 6 hens out of the yard. I have no idea how they got out as the sexlinks have clipped wings and the buffs seem to0 hefty to get over the fence. Could they have gotten under it? I got them all in and locked them in the coop with plenty of food and water until I can figure out what to do with them. Any suggestions or advise on this situation for a newbie? Thanks!
