My 2 girls are 6 months old and have been laying for 59 days. One of them at the beginning was having trouble w/ similar problems as yours (soft or shelless eggs, etc,). I thought it was because they were using up their "grower feed" and not getting the right nutrients to produce a hard shell. As soon as I switched she didn't have anymore problems and that was about 5 weeks ago. Also she would always drop the bad ones in the poop board. The only stress she may be under is her sister is stealing her sleeping spot on the roost when it is time to go to sleep. Sometimes she is able to get it back and sometimes not. Everything seems to be normal except she is eating grit like crazy and we found her laying on her back on top of a cement block w/ feet in the air. My son found her that way and said she was there for over an hour. Do you still think it could be just a hiccup?
