I have a hen here (a red cross) who is around 18 months old, she had been laying quite large eggs compared to the other girls, and recently one got stuck and broke in her vent, which prolapsed. I managed to sort out the prolapse and get her back to normal with a few days of TLC and low light. Now that is she is back laying again (she was off the lay for maybe a week and a half?) the eggs are still huge but they are softer than usual and breaking before they come out. I have read that I should increase her calcium, however I'm worried that to harden those shells will cause another prolapse. Is there some reason she might be laying such abnormally large eggs? Is the risk of another prolapse greater than the risk of an infection from the broken eggs? They are easily 30 - 40% larger than all the other eggs and before the prolapse her larger ones were "body checked" with a thickened band around it. Aside from the egg issues, she is foraging, eating and drinking as usual, although she seems a little depressed, keeping to herself, tail held a bit lower than usual, and putting herself to bed early at night. Any tips or advice would be well appreciated.
