Several of my local friends all have hens that each lay 1 egg / day. I have 6 hens and I am only getting 2 eggs / day instead of 5 or 6 that I would expect. All of my friends have a Rooster where I do not. Will the presence of a Rooster help the hens lay? I feed Laying crumbles, crack corn, and oyster shells and they have a constant supply of clean water. Any ideas?
