It took me another couple of days to apply enough layers of thicksotropic silicone to form a more rounded shape over the legs of the turkey. Once these had dried, I had to make another plaster jacket to fit the new shape. I realised last time I had forgotten quite an important part of this process, which is adding a layer scrim over the first thing layer of plaster before building it up completely. I also decided with Andy that it would be better to make four section of the jacket this time round, rather than 3, so it would hopefully make them easier to remove and allow me to be more careful about it (so as not to disturb the cast inside next time!).
You make the four jacket section by building a clay barrier around a section at a time, then removing it and building on from there (making small indents on each one so the jacket sections will slot in to each other eventually). Once one section of plaster has been built up and allowed to set for about 30 minutes, it's important to remember to paint the exposed edge of plaster in either a clay and water mix, or simply coat it in Vaseline. This is to stop the sections of plaster jacket sticking to each other when it comes to removing them.
I am will now go in tomorrow and separate the layers and hopefully get my first cast. This time round I plan to initially swirl a thin layer of latex around the silicone cast to form a skin for the turkey, which I plan to cast in wax.
