My suggestion would be to feed the foals first in front of him and after they’re full, give him his portion. He’s refusing to eat until he’s sure his siblings have been fed, so once they’re fed, he should be happy to eat.
An alternative is to explain to him that if he doesn’t eat, he’ll become too weak to look after his siblings and so he wouldn’t be able to look after them properly.
The last ditch option is to give him only food that he can eat - since he’s giving his food to the foals, that implies they’re weaned fluffies, but considering the size differential, only just weaned, so they’d be unable to chew hard adult food, like dry kibble or carrots, or unwilling to eat bitter foods, like grass.
IC: thank you stranger! these are all great ideas! I’ll see if they work. I’ve been feeding them at the same time. it was pretty short sighted of me. I’m not an experienced fluffy owner you see, but my empathy gets the best of me when I see animals in bad conditions…
If you’re feeding them all at the same time, then the foals are eating all their food and Doilee’s, so either you’re not feeding them enough or the foals are being greedy and overeating.
The former is easily fixable, the latter will require explaining to the foals that their big brother is going to go ‘forever sleepies’ because they’re taking his food.
If a foal doesn’t care and continues to takes Doilee’s food anyway, then disciplining is required. How you do that is up to you; giving Doilee adult food only is a hugbox option, but I’d suggest segregation and starvation so that foal can feel the hunger pangs (i.e. tummy hurties) that it’s giving to Doilee.
If it still doesn’t learn after that, then give it up to the shelter or just destroy the defective product. Abandoning it in the wild or the streets is just poor ownership and contributes to the feral population problem.
IC: I’ve been giving them carefully measured portions of nutrient dense milk every 4 hours per instructions from the vet (including Doilee as I’m concerned his teeth and stomach won’t be able to handle solids due to the starvation…) Doilee pushes his dish to the foals and when I try giving him the bottle he takes it as a signal to hold his siblings up for a drink… I don’t want to use cruel language to describe it. misguided, maybe? the foals are overweight for their age. sluggish too… I’ll seperate them after I’ve fed the foals in front of Doilee, and then bottle feed him alone in another room and see if it registers.
An unselfish fluffy? That’s almost unheard of in the fluffyverse
OOC: from what I’ve observed, there is no medium for fluffies. they are either destructively selfish, or destructively selfless. defective species :3
hi we arent roleplaying here also are you over 13?
OOC: I do not answer questions from people who do not commit to bits. be funnier

I wonder if the mods would get a friendlier response, or at least less resistance to your age check questions, if there was some visual indicator on their post profile images that you were mods?
