Poorly chicken

[Pom Pom and Lavender]

Hi all. One of my silkies, Pom Pom, has been consistently laying eggs with paper thin shells for over a week. Usually she lays every other day and the eggs have always been slightly elongated, but lately shell less and very thin shelled eggs have become much more frequent. I just had two in a row! Two of them have stopped laying for the winter and one is still laying good eggs every other day. Pom is about 2 years old ish maybe younger. 
 

I’ve looked online quite extensively and there are so many factors so I bought liquid calcium and added that to their water. They always have access to grit and I’ve seen her eating it! They have omlet crumble and some treats a couple times a day and they free range all day too. 
 

I’ve read on the various health conditions and she seems absolutely fine - eating, pecking around, drinking, normal behaviour! I have seen that this could be to egg drop syndrome or infectious bronchitis, but if so, are the chickens ill with it ?

thanks for your help x

I would stick to adding some kind of tonic to their water .

You could also try a different grit - mine now have Gastro Grit and they love it.

As she seems to be doing normal chickeny things I would say she probably isn't ill, but I would keep an eye on her just to be on the safe side.

I agree with @Luvachicken. Also when did you worm them last?

[Pom Pom and Lavender]

Thanks both. I always put tonic and recently a vit d and calcium supp in the water. I will try gastro grit though thanks!

 

Last wormed probably about 2-3 months ago
