pooping

We have a new fawn and we are bottle feeding it. He did poop once but it has been a couple days and he still won't poop again. Is there something I can do to aid him?

My bottle feed fawns are only pooping once a day, Trying warm towels, should I be concerned? any suggestions?

We have a doe fawn that we are unable to stimulate to poop. It is 4 am and has been over 12 hrs since last movement. We have tried a lot even using a q- tip to try to coax her into going. What other things can we do to help her? We are feeding straight red cap. Please help or suggest. Thank...
