I'm brand new at this - I have 8 hens (4 breeds) that are almost 24 weeks old. One is laying everyday, beautiful little eggs with very hard shells. I have 3 other hens that seem ready to go also. This morning I found on the poop board under their roost, a soft "egg" that was filled with all yolk, the "shell" almost transparent - the whole thing was "jelly like." Looked like she layed it too early, especially since it came at night. Should I worry, or is this just a hen getting ready to start laying? Thank you for any feedback!
