Stuffed bird

[animary]

According to Brodgar:
"Place the Raw Stuffed Bird in the oven or fireplace, then fuel it with 4 branches and light it. It will take roughly 20 minutes for the Stuffed Bird to bake."

I put 8 stuffed birds in oven fueled with two blocks. Next day they weren't even half cooked; put three blocks in and relit. Today they were about 3/4 done, two more blocks and lit it again. What will I find tomorrow? (Probably ashes.)

This doesn't corroborate Brodgar data.
