my barred rocks have not laid an egg in almost 3 weeks now. they are 7 months old are not molting on the same feed(layer) that they have been on. they started laying at 5 mo. no signs of any sickness. also my delawares, black coppers, ameraucana's and rhode island reds have slacked up. even my white leghorns have slacked in their egg laying. any ideal's on what is going on with my girls? they are all in seperate pens. the reds have been molting and are starting to get their feathers back now, my ameraucana's are molting, my leghorns are getting over fowl pox, the rest of them are first year layers and avarage from 7 months to 9 months old. I just dont understand what is going on with them. I understand about the molt and the fowl pox causing them not to lay but the others just up and quit.
