Hi everyone, hope you can give me some guidance or assurance. I have 5 Barred rocks that are 23 weeks old. One of them started laying small eggs a month ago. She gave us about 9 tasty little eggs then started giving us shell less eggs ever since. So far about 18 shell less. They are eating layer pellets with 4.5% calcium, have free choice oyster shells, free range about 5 hours a day, have clean fresh water with a little ACV added and couple of handfuls of cracked corn before bed. The yolks are all very orangey yellow and look good. The girls are all very healthy looking and active including the one laying shell less eggs. I see no mites or worms. None of the others are laying yet but are showing signs. Is this just a case of young hen getting used to laying eggs? Should I find another source of calcium? Am I impatient? Why normal shell eggs then shell less? Thanks for reading.
