One of my chickens is laying either a no shell egg and now a soft one (see attached). I just recently integrated 2 new members into the flock, so I don't know if this is the cause or not, but it has me worried. I did the standard 20 day separation, etc. and pecking order seemed to work out fine, and they are now all sleeping in the same house. I did just all a probiotic to their water to see if it made a difference. Any cause for concern? The other 4 are laying just f ine.
