Chicken mid-molt. Posted on egg laying forum but no responses. Worried I am heading into egg bound issues. She is acting totally normal, eating, drinking, running around but this is the second strange mass of egg shell type material she has passed inside a thin shelled egg that is broken when I get out there. I am offering oyster shell all the time. I know its a strange time to molt but both my birds are molting and a few years ago the same breed - Isa Browns - molted at this time of year. I had the same problem and one of them died from egg binding. So far she is obviously passing material out of her body but I am worried it is building up and will cause a blockage. She did lay a good egg last week but since then has been egg free - I think. Hard to tell with two birds. The other seems to be having less feather loss so I assume she is the one laying every other day or so. Someone did lay a very small egg with no yolk during the past month.
