Hello, Three Swedish Flower Hens got to laying age a few weeks ago. One of them has been having issues: - Some eggs with no shell - Some with shells that are deformed or oddly shaped - Often goes to the nest box for an hour or so, but comes up empty - Seems to act lethargic/depressed when having trouble getting an egg out, but seems good otherwise - Never seen her eat oyster shells, though the other birds do I was hoping this would quickly pass, but it's been 3 weeks now. When we notice her acting depressed, we've been providing some homemade yogurt with oyster shell flakes mixed in. Not sure if she's lacking the instinct to supplement calcium, is sick, or if this is normal? All three of them forage like crazy, but they eat a good amount of their layer feed as well. Any thoughts/advice would be appreciated. Thanks!
