I would go to Tractor Supply(or similar) and get a bottle of tylan50. ""I"" personally give mine 1ml oral once a day for a few days(draw 1ml out the bottle with a needle, take the needle off and ease it in the corner of her mouth---holding her head back and hold till she swallows). If she is not eating again ""I"" make a warm watered feed mix---using chick feed or factory layer feed(gotta use feed that some-what dissolves in water)use a bigger syringe and draw liquid "gravy" off and ease it into the corner of her mouth--I do dissolve a baby aspirin in it some times---I feed this for a day or two offering her the warm feed---on a spoon---if her strength starts building up she will probably eat the warm feed/water mix. If she is not eating her body temp will be low so I place mine of a older(stays on all the time) heating pad on low---with a towel laying on it so its not to hot---I place this in the bottom of a plastic tote and put her in it until she starts eating some. When/if she perks up """I""" then worm if her weight is low(boney)---I have brought back several near death doing this---yes some do die but I tried..
