weak kid

Hello, I’m a new goat owner ! My husband rescued 2 goats and a lamb from a slaughter and were told they were wormed which I am having a hard time believing they were okay the first week, now one is super sick!! I gave them dewormer and slowly giving him bounce back but his gums are almost white...

Have kid wrapped up on heating pad inside with heat bulb. Used hair dryer with heating pad then put her under the heat bulb. Rubbing her limbs. She isn't looking good. Any other tips to save this baby 😭
