I have four hens, two are 4 and 5 years old; the other two are just over 2 years old. Since spring, the egg laying has been in rapid decline, and since July, we've had no eggs at all. We are currently in a molt, so I realize that we aren't going to get eggs now - but my question is, can non-laying hens (my 4 and 5 year old) effect the egg laying behavior of the younger hens? It just seems like everyone in the coop is in retirement! Anyone else experience this with a mixed aged flock?
