I bought an 11 month old hen about 5/6 weeks ago so by now shes 1. When I got her she laid me large eggs everyday! In the past week the eggs have gotten smaller and smaller then today, NO egg at all. Will this change? What happened? I feed a pan of food with mostly layer mash and a little bit of scratch. She goes NUTS for the scratch, could she be just not eating enough of the layer? Any advice is great. Thanks!!!
