Since she's not mobile, you'll have to clean vent and feathers at least once a day.Uhh.. so apparently her vent was blocked by rock solid feathers. i found eggshell fragments and cucumber peel around her vent, and it was completely blocked and pretty messed up. I used water to loosen her feathers and eventually I had pulled away loose feathers and weirdly squishy eggshell and her vent seemed red. Honestly, it may have been normal, but I don’t know because I don’t generally look around there. I'll reply tomorrow.
If there was a soft shelled egg, then I would get some extra calcium into her. If you have TUMS, you can give her 1 tablet a day. Calcium Citrate with D3 (Caltrate) is better, but do what you can.
Does she have a bad odor like infection, a discharge from the vent?
