Big eggs

One of my girls always lays very big eggs, today she laid one and it weighs 105gram. I am worried about her laying such large eggs over a short period of time. ( it makes my eyes water just thinking about it). Will it do her any harm. After she had laid the egg she just carried on as normal. running around and was straight for the food again.  Am i just worrying over nothing ?.

 Hi Jeanette
How old is she

One of my hens used to lay huge double yolkers the biggest was 119g . She settled down to lay normal large eggs. The huge eggs are not good for the hen but as there is nothing to be done it`s best not to worry, just keep a watchful eye on her.

Ps not to generous with the treats as fat hens have trouble laying.

I have 4 blubelles and one got egg bound because the egg was enormous. I found her last Sunday straining away.  2 baths and vaseline did not work, I couldn't get my finger in far enough to manipulate anything. The choice was put her out of her misery or try to break the egg. We did the latter because she's worth a try as she is this years hatch(feb i think) so anyway, we made a hole in the massive egg, syringed out the contents and found another normal sized egg in the middle of that one! 
This we also had to break, syringe out everything and removed every bit of shell. Then we rinsed her out with TCP solution cuz that's all we had and put her in the conservatory to rest.
She was much better the next day and the day after that she went back up the allotment with the others and carried on laying.
I always wanted big eggs but not if they are going to do that to my chucks, so now I won't encourage it by extra treats or anything, just let what comes natural.
