I have a 2/5 year old aylesbury female duck. The one in the right side:
.
She started laying at 5 month. She ve been getting calsium since she started laying. She had normal daily laying. Without any pain. She eat normal and she was a happy healthy duck. Sometimes she laid two eggs in a day.
But 10 months ago. She laid her first soft shell egg.
I thought its normal.
But it continued in 1 soft egg in a week.
And others had a thin shell Too.
As the time went by , it became weird eggs with strange shells.
Sometimes a few uncompelete eggs stucking together.
her egg laying amount was decreasing too
It was getting worst
This last month , she only had 1 egg with some weird eggs like cream in her poop.
She a eggs with a very strange shape Last month and stopped till yesterday with another strange egg.
Like many creamy egg shells sticking together and made this.
She had a xray photo recently and was compeletly healthy. She never molted like my other 3 ducks and she have broken garbage primary wings. But her feathers are waterproof
I dont know whats the problem
Please help me if you know
I just want her to be healthy
I attached photoes of her last month eggs.
And these are the eggs she laid this month and yesterday:
