Of my nine hens I am getting 5 eggs a day now. They have are around 24 weeks or so. I bought them a month ago. Today I let them out to free range for an hour or so while I was out working in the yard. I saw one in the weeds acting funny so I went over and sure enough she laid an egg. I waited about 5 minutes and went to pick it up and it was pretty soft. Not like jello but definitely not as hard as normal. I am assuming a "normal" egg is pretty hard after it has been laid? I went ahead and pitched that one over the fence and when I turned around there was another very soft egg in the yard 10 feet from where the first one. I didn't see who laid that one but a couple of the other hens came over and started pecking at that one. They were eating it before I could pick it up. I went a picked up the shell from that one and it was like rubber and fell apart. I know when pullets first start laying their eggs are not always perfect. I have not had one single soft egg (that I have seen evidence of) in the coop. I guess it is possible if this has been going on they are eating it before I found them??? I have been planning to build a feeder for them to keep oyster shells in but have not gotten around to it. I have been putting a couple of handfuls of oyster shells in the coop on the feeder that I have grit in every few days or so as needed. I know typically you don't get two normal eggs in a day but the odds of two different birds laying to very soft eggs a few feet from each other at the same time seem pretty slim also. Not sure what to make of it. Both eggs appeared to have a normal yolk inside and were normal size just very soft.
Short of some type of video system is there anything I should look for as far as evidence that one or more of them is laying soft eggs which are then being eaten?
