I have 8 Prairie Bluebell pullets that are 6 months and one week old. They are free range in a 100 x200’ contained area. They have grass, sunshine, dirt, scratch grains, bugs, food scraps, Nutrena layer pellets and crumbles, calcium supplement. They have grown well and have great feathers and act fine. However, I have not gotten a single egg yet! They have been visiting the nest boxes for weeks and I have combed their outdoor area in case they were laying outside, but there is not one egg. I don’t believe a predator would be eating all 8 eggs every day without a trace and leaving the 3 brown eggs from my mature birds. Has anyone run into this before? Is in not that unusual? I have never raised birds that haven’t been laying by 4 1/2-5 months of age. Any suggestions besides just wait..
