I have a hen who is just 1 yr old as of last week. She is a Gold Star and has been laying an egg usually 5 days on one day off-very reliable layer. This week she hasn't laid anything- I did find one large egg in the run (unusual). I saw her in the nest box many times throughout the day but never found an egg from her. I 'think' the egg in the run then is likely hers. This egg happened on Wednesday. She looks completely normal, eats and drinks. Comb is a nice color, no funny sounds from her breathing. When I held her, her abdomen was squishy. I compared her to a couple of other hens- not very much different from them- maybe a little larger squishy area. Any ideas? Could it be that the mystery run egg was tough for her and she's recovering from laying it now? Any ideas are greatly appreciated.
