I have 46 laying hens.they are still pullets, 27-30 wks old. they are Rhode island reds, barred rocks, buff orpingtons, delawares, and a couple of weeks ago i got 14 eggs in one day, and the next day, 6-7ish, then the next day 3, then 1, then back up to 2-3-4 a day now, what happened to them???? i'm feeding them real good, layer pellets, table scraps, breads etc. and fresh water always, what could be the reason they cut back on egg laying??? and why are the rest not laying yet???
