I just let the hens out and collected eggs like every morning. Again today I got a soft shell egg, I don't know who is laying them!!!!! I brought it in the house and took a look at the egg inside, and it has a bullseye. At first I didn't know what it was so I had to look it up through forum pages and came across a link to some images. here is the link! http://4hembryology.psu.edu/fertile.html the white dot looks EXACTLY like the second photo. with this said I don't have a roo in my flock, all my hens are red. well except for one who is lighter, look like a golden comet. Is it possible I have a roo hiding in the mix?? kinda confused...any help offered will be appreciated. This btw is the second soft shelled egg I have gotten in the last few days, I have been giving them yogurt and cottage cheese etc for calcium but it doesn't seem to be helping who ever is laying it. all Hens look the same size, no one is sick and none have mites etc...they are all on layer pellets and I give them a mix of scratch and premium bird seed mix I got from the feed store. I usually give them this mix int he am in the run for something to do and a tiny bit at night to make them come in for the night.
