Yes, he had wonky leg and agree they probably gelded to help him not carry the extra weight and slow his maturity down. Some stallions do throw traits just as mares do but a wonky leg like he had at birth my thoughts would be it was caused due to how the foal was lying during utero and not something that would be passed on, but I am no expert.
Agree with Pam smaller stables are probably not set up for colts. Also, what is nicer for the horse a gelding that can be with a mate in a paddock or a colt who has to be by himself and does not understand why he is being told to pull himself together and act like other horses when he gets excited due to still being a colt.
