I have 11 pullets 7 RIR and 4 Deleware. They are 22 1/2 weeks old. I started getting eggs last Tuesday. I got 1 that day, none on Wenesday, and have gotten 1 everyday since last Thursday all the way to today(Monday) where I got 3. All the eggs have been laid in the nest boxes and have been hard with no blood issues or shell issues to speak of. However, yesterday I noticed an egg that was a bit rough like sand paper on one side in particular. I researched and read it could be excess calcium. Today one of my three eggs was covered in white speckles and didn't have a sand paper feel to it but didn't feel smooth like the other two collected. From what I understand this could also be a sign of excess calcium. I feed Purina Flock Raiser 20% protein, oyster shell free choice, scratch grains every now and then maybe 3-4 times a week a few tosses. They get out of the run everyday to eat grass and bugs in a controlled, fenced in 3/4 acres of a 4 1/2 acre lot. I understand new layers will have problems sometimes at the beginning. But this is a bit different then what would be considered common new layer issues from what I have read. If what I am feeding causes excess calcium; then how in the world to people commonly give layer feed, free choice oyster shell, and sometimes even egg shells and not have issues?
