So I bought a 4 month pregnant ND doe, when I picked her up from the farm she was huge, and when I went out to her pen the next morning she was pretty svelte. There wasn't anything in the straw to indicate she had aborted, but it's been a day and a half now and she's still not looking like she did originally. Not skinny, but not potbellied either. Could the stress of moving to a new place have caused this? And what can I do about it?
