One poorly chick been to vets given vitamins and electrolyte mix, is taking few drops but difficulty getting it in even with syringe. Is now chirping less and just sat slumping under the heat other chicks lying with it to keep it company. Is chirping less and just lying there most of the time. Eating and drinking small amounts not like the otter two, have mixed some chick crumb with water and liked that, but the other two polished it off as well. V worried it is going down fast any advice or help at all greatly appreciated. Thank you
