My wife and I have 4 ISA brown hens. They have been laying for little over a month now. At first we had a few soft eggs and a few tiny eggs but all 4 have been laying good eggs for the last few weeks. The last couple days ive found a soft egg in the coop. Today i had two soft and two good eggs, i checked again late morning and found a third good egg. So i had a total of 5 eggs from my four chickens today. Is it possible one could have layed twice? They have a good layer feed and i have oyster shell avaliable to them. They dont get many treats or scraps. The treats they get are a forage mix that i grow for them that has grasses and clover or they get some black sunflower seeds. Once in a while they get lettuces, kale, or spinach greens.
