Coprophagia in a 4 1/2 month old foal? Cause for concern?
I've observed my filly doing this on several occasions (most recently today), and wondered whether this might indicate a dietary imbalance of some kind.
She did it when she was first born (during the first week or two), and I ignored it because I knew it was a natural thing (getting that "good bacteria" into the gut, acquiring mom's immunities, etc.), but I wonder whether this behavior should have faded by now.
She has been nibbling on hay since she was a week old (obviously couldn't digest it at that age), and has always had a rather voracious appetite for hay; she gives her mom a run for her money when it comes to hay consumption--which is saying something! The BM where I board them hasn't started creep feeding her--at this point she just shares her mom's grain (not ideal, but she will be weaned in about a month, so that should make things easier in terms of getting the "age appropriate" nutrition into her.) She is in good body condition, but is not fat; I can feel her ribs.
She is very curious and very oral, and licks the boards of her T/O field (but she and her dam are both VERY "licky", they also lick humans--so I don't know whether or not this is significant.)

It is normal for a foal to eat mom's manure. In fact when I was raising an orphan I was told by the vets at my university vet school clinic to put fresh manure from a mature mare where she could get to it until she was strong enough to go out with her grandma.
