Hey guys, I have a compost pile (mostly horse manure and grass/hay )but last year I threw some old pumpkins and various other rotten squashes and stuff people gave me on the pile. Now of course they grew and I have stuff I cant identify. I have some regular round pumpkins growing and turning green to orange but I also have some squash type that is green then turns yellow/orangish but only partially. They aren't big like pumpkins and don't finish like pumpkins. I cut one open and it is real firm and has seeds like a pumpkin. It could be some type but I have know idea. Any body know. The pictures show how they start and how they look turning colors. (they only seem to turn on the side facing the sun) They have been this way for about two weeks. my foot is for size reference.
