I have a 1 year old BR laying fragile and bumpy eggs for the last week or so. The other girls the same age are laying fine egg, including the other BR. I also have pullets just laying and a young rooster who was supposed to be a pullet. Surprise! This BR tolerates him but the other older girls will have none of it. I've also begin letting them out to free range in the afternoon in recent weeks. They do get a good quality layer feed. I add oyster shell from time to time to their food but not with every fill up. All of them appear healthy and happy. Any suggestions or advice would be appreciated .
