Ive never forced a molt, but molting does affect egg laying. All my girls just took a holiday, every single one. 3 big pekins never have, (just been occasionally inconsistent) and my little calls never lay regularly, they always have trouble. I tried everything - sitting up for an egg thief, adding calcium, adding B1. There were no eggs until this week when soft shells started showing up.
Then my mum in law suggested warm porrige. We are experiencing severe weather, so I made a batch of oatmeal and gave it out warm mixed with their layer pellet. 4 eggs the next morning! I did the same last night, 2 eggs this morning. I didnt make it tonight, I wonder what I'll find tomorrow?
I used rolled oats, quick oats and oat bran cooked slowly in water with a dash of milk and golden syrup.
