One of my SS was acting sickly this evening. Wings and tail dropping, feathers fluffed up, she was off by herself acting very sleepy. I checked her crop it was fine so I was looking her over and seen that she had dried poop stuck to her vent feathers and her vent feather were spread like she was trying to go poop but nothing was coming out, at first. I gave her a good soaking in warm water. Then gave her some yogurt, ACV water, Molasses water and a little bit of mineral oil. After about 10 to 15 minutes she laid a completely shell less egg and a little tiny rubbery egg. She is a year old today so it's not like she is new to laying. They have free choice oyster shell and this is the first time any of them have laid and odd egg. Will this harm her?
