Im not saying its impossible for humidity to cause a nail to fall off, im just saying I think its more likely that it fell off from him digging or something

Hi, would be absolutely amazed if low humidity caused a claw to fall off!? I wouldn`t be at all surprised if he/she caught it on something, keep an eye out for any swelling in the toe which would indicate infection (in that case antibiotics may be needed). For now you can use a diluted solution of iodine (one part iodine to fifty parts water), just dab a little on daily. The claw will regrow, it will take a couple of months or so.
