ok guys, i lost a sweet hen today to a snake, i need ways to keep them out, she was a broody i was trying to break, and had no eggs. The coop has to be open during the day, its a metal coop, hot as heck in the summer- snake repellents? every year its a problem, but this is the first time i lost a hen to one, i need ideas? I tried minnow traps last year, didn't work- this guy was big, so a small trap won't work
