Unusually large droppings

[motorboat]

I have noticed some rather large, egg sized droppings in my pen lately. Today I saw a young (1 year old) game hen drop one. It was shocking how large it was. It seemed to be about the size of one of her eggs. It was solid, not runny but it had a lot of black in it. Not sure if it stood out because it was so large. Anyway, any thing to worry about?

I bought a bag of sunflower seeds. Never had a problem with them eating them but that's the only thing new that coincides with the large droppings.

Thanks
