Chooks, tail feathers and bowls

We now have 2 chickens in the bottom corner of our garden, I built a run and chicken house out of left overs from house renovations, I think these are black orpingtons chickens, one of them was laying eggs as soon as we got her then one day the neighbors dog barked and she had to go see what the noise was about, over the fence she went it must have been right into the waiting dog as she lost her tail feathers before she found their wood shed to hide in, we only got one more egg now I think the experience has put her off laying for a few days.
I have been standing in a shower of wet wood shavings for a few days rough turning wet wood for it to dry I wanted to do some finer work and took some thin scraps I thought were a bit useless along with a piece that had sap wood.
I wanted to see if I could do hollow form by gluing 2 pieces together, 3 of the pieces I had were only 20mm thick so with a slight hollow became the bottoms and one top, these pieces are 220mm diameter the tall one is 63mm and the unfinished one stands at 53mm including the ring I glued on, at present I am contemplating how to hold the bowl on the lathe while I finish the top ring.
The wood is not entirely dry, there was movement overnight while I turned them so the wood has become very thin as I had to re turn turn them, they now make a good drum.
I wanted to make the opening large enough to be able to see the grain of the wood inside the other one won't be so big but then the grain of the wood is better on the top.
