Aww Ema, i'm sure Billy Nibbles will be fine.
Pearl has no ears she was like that when i got her. Abigail has a stiff left foot. She had it when we got her. Pearl was 3 1/2 and Abi was 4 when we bought them. It looks like it was broken at some point but then healed but didn't heal right. she can use it to get around but she can't grip with the toes, they are stiff, she can't separate them. It does make her slower than the others but she can still get around. When climbing she uses three legs mainly. Bailey lost a toe in a fight. It happened at the time when i had all the bad fighting and trouble when i put all my chippies into our first aviary last june, so on his right back foot he is missing a toe. It didn't affect him at all so i think Billy Nibbles won't notice his missing toe.
