Hello all, I have six hens, one Black Australorps is the only one laying yet. She laid nine eggs and stopped. I checked her vent and it seems normal. I did notice that she doesn't seem to be seeking out the oyster shell like she was either. It is in a separate compartment of their feeder as is the grit on the other end. Neither seem to be going down. Any suggestions? The rest of the hens I feel should be laying soon if not already as well. I'm feeding a mix of Layerna, Red Winter wheatberries, rolled oats, flax seed, diatomaceous earth,nutritional yeast, and kelp powder. I will be adding corn very soon to my mix as well. Everything is organic in my feed except the Layerna. Thanks!
