3 days ago I rescued 3 baby squirrels out of a tree that was cut down. We tried to find mommy and waited for her to come and she never did so now I have them. They are probably about 3 1/2 weeks from what I have seen. I've been feeding them, day 1 and 2 they didn't eat much, last night and today they've eaten more but still not as much as recommended. I'm worried that they aren't eating enough. They are pooping and peeing, they are extremely active and chatty. I weighed them yesterday and we have 62g, 68g and 70g, today they are 62g, 66g, and 70g so now I'm even more concerned. What do I do to get them to eat more?
