My little palomino pinto is just starting to mush up in back and bag just starting, About how long after she starts to mush up does she have. Her due date is end of March first part of April we think, The lady that had her last year said she foals early and gets a large bag. She is very uncomfortable when she lays down you can see the baby really moving. She hasn't showed any signs yet like my mare did last May. The laying down all the time, kicking self in stomach, walking floor,she eats off and on (nippling)
