I am a first timer and today I noticed that two of my month old New Hampshires have a bit of blood on the webbing between their toes. It almost looks like cracking from dryness. It's not dripping, but I am afraid the others might peck at it. Any ideas what it is and how to take care of it? Their bedding is shavings and they have gone outside a few times. Other than this they have been doing great. Thanks!
