My hen is going through the same thing now, she passed a collapsed soft egg shell. If I get aqua mox, what would be a dosing schedule? And how is the chicken doing? This thread started on April 2..Looks like a malformed, soft shelled egg. I don't see any lash material. May just be a glitch, or if it continues could indicate a larger problem. I would give her a calcium citrate + D once a day, see if that firms up the shell. It will also help with contractions and help her pass any more that is still inside. Passing those can make them fell pretty bad, they are hard for them to pass. If she doesn't perk up some in the next day, I would also start her on an antibiotic. If there is egg material in the oviduct from a broken/ruptured egg, that can cause infection (doesn't always, but definitely a risk). Amoxicillin can be gotten as a fish antibiotic without a prescription (aqua mox).
