My son (4) went out Sunday to get eggs and found a snake. Upon me and my sister running over to kill it, we discovered 2. We killed both and realized one was a rat snake and one was a moccasin. I realize the rat snake (might have been a king snake) is a "good" snake," I have small children and don't want them to get bit. (It FREAKED my son out, he went and crawled up the swing set and stayed in their club house). I've read sulfer and crushed egg shells are good. (1) Where do I get sulfer (2) Will it harm the chickens in anyway? I've gone from 17 eggs a day to 4 so I'm assuming my hens are freaked out also and may be laying somewhere else or we may not have gotten all the eggs and may have an egg eater, but from 17 to 4 seems a bit much for one snake. . .
