While watering my silkies one of the mice nests in their pen got flooded & out popped 4 mice that are approx a little under 2 weeks. I cant get to the store till around 4, & I was wondering if there was something else I could give them till then? When I bred rats I used plain soy milk mixed with a little bit of Ensure, which im out of & need to buy, but im not sure about what else I can use. I have lactating mares & goats that I can milk or I have foal milk replacer & plain cow milk from the store. Would any of these work?
