Please help, our White Leghorn (3.5 years old) has laid two eggs without a hard shell (membrane and yolk only). She seems strained when she has to lay. Epsom salt bath gets it moving and she’s back to normal as soon as the egg “passes”. White discharge we think is an infection, been giving her amoxicillin starting today. This has been an issue in the past. Any recommendations? We do have a vet that treated her for a reproductive tract infection last year around this time.
