I agree with Arborgoats.
I don't mean to Scare you
Pooch pics may help, tail up naturally, close enough to be clear with udder area. Or you can get a preg test done on them to verify.
usually by 3 months along, some members can tell.
Until you are sure they are preggo or not, treat them as if they are.
I see a bowel full of feed, if they are not use to it, I would start them out very gradual on it or they will start scouring and get an upset rumen, this is with any feed change or increase.
Get a fecal right away, so you will know what and if they have worms or cocci and how treat.
How are their gums/ lower eye membrane color area, white, light pink, or nice dark pink/red?[/QUOT
Very pink
