Thank you for explanations, it helped me a lot as legs are still quite a mystery to me (I must learn so much, it is just not enough time to learn it all as soon as I need it to learn, but I am learning, I am).
So far I only know for sure that he needs farrier ASAP. And then deworming and teeth checked (He is missing 2 front teeth already after the kick when he was 2 yo). And then we shall put his rehab program together. It will take a long time to get his hoofs back in the right shape and angles, and even more to get his fetlocks rehab to the normal conditions. (For Puika it took over 12 months to get his back right leg in the best possible condition) But it is even clear for me that this boy will never jump high again and will be suitable only for some mild, easy riding.
About wintertime. Yes, our winters are harsh in comparison with UK, but I can not see any problems why he can not make it here.
First, his previous owner had told me that he had lived with other horses without any problems. In my trainer’s stable 2 stallions are living and they do live together with all the girls in the same wing, and are handled by children (and they are not so calm as this boy actually, one is Quick Star’s son and a real handful).
This old boy had been lived with mares around in his younger days and had been trained to behave in the right way - I do not have any info that he has issues in this field. His previous owner (years ago) is experienced horse person and would not tell lies about his good behavior around mares.
Actually it is ME who is jumping in an unknown waters and is worried about not having experience with a stallion.
We shall put him in the far end box, and the only thing to make things easier will be to take him out last and put him in first so he doesn’t need walk past other horses - mares or geldings. It is our plan so far.
The second - we are quite lucky having a huge barn. It is T shape, and once I had measured it and counted - there is space for at least 80 horses (it does not mean that I am planning to end up with 80 :D) so if it will not work, I can move him to separate wing with just one gelding, Guido or Puika for company without any troubles. So far I’m using only one wing out of three, so enough space to keep somebody in quarantine or just separate like stallion. I even have there some empty rooms with brick walls so if he will be really restless, he will safely be kept in one of these.
About breeding - see, here we have quite strong rules - it is not for me to decide is he suitable for breeding as a stallion or not. The org who is holding studbook and issues certificates for stallions decides. It is based on stallions confirmation (which is terrible at present moment) and/or on his offsprings.
This stallion had certificate ten years ago, and had quite high marks for his confirmation then. Now… As this stallion has now over 10 foals who are grownups, it is easy for org to decide is he worth breeding or not. They judge confirmation of his foals, inherited problems, temperament/character, rideability and achievements and then say their final yes or no.
Of course, it is still a free country and you can breed with a stallion who has no certificate, but actually I do not know any case of such practice here, except real accidents (like youngsters break out and do the deed by themselves). Without certificate you can not get full pedigree of the horse, and who would buy a horse without proper papers? Nobody wants to take such horses here.
If stallion has certificate, it is up to me to decide do I want use him for any of my mares or not, but at present it is not even a question. I’m trying to put all this paper-shuffling thing into my head right so there still be some gaps in my knowledge at present moment.
I’m so sorry, I know my thoughts and ideas might be really annoying probably for many of you, but I better will ask and ask again so I can learn quicker - at current economic situation it allows me save at least some of hopeless ones. It is not much, but at least it is something.
