Hi everyone, I keep 5 BR, 5 BSL and have 12 18 week old RIR crosses who should start laying very soon. My BR's & BSL's are about a year and have been laying since they were about 20 weeks. I get 8-10 eggs a day. Here is the issue, I keep getting ( for about the last month) one egg that has a VERY pale yolk. The shell is normal, all my girls get the same feed that includes ground flax. I am not seeing any unusual poops, no one appears ill or lethargic. Any ideas?
