holy smokes 1k for a hen, i am sure the specialist wants to do it immediately..........
Our friends beagle came to stay and didnt know the house rules on chickens, long story short, our resident belgian d'uccle ended up hopping on one leg, the other was broken, i couldnt feel a fracture or a dislocation but when she couldnt put ANY weight on it i let my wife who is in nursing school practice her splinting skills - i suggest you save yourself $1000 and splint the leg yourself.
Get a couple wooden kebob skewers
Cut the to the length of the broken portion of leg, then attatch a piece of medical tape between the two skewers at the top and bottom so the skewers are held parallel.
Then wrap the leg with some material, we have yellow sports wrap that i used on my ankles when playing soccer
Then cradle the hurt part of the leg with the splint.
Then re wrap the whole leg with more material, splint and all then wrap all of that with medical tape. Tight enough she cant peck it off, not too tight to prevent blood flow.
She will have a fairly immoble leg - thats the point, she will continue to struggle to put weight on it for a good week and a half to 2 weeks, we changed the wrap once in 4 weeks because it was nasty dirty from her being outside in the coop. The leg healed, she still sometimes favors her left leg over her right but 7 months later, she is the best momma I have and is fighting fit.
Apart from the first night, she was outside the whole time, days 2, 3 and 4 i had to manually place her on the low roost at night, when i woke up, she was down and hobbling around with the rest of the ladies, day 5 she got up there on her own.
DONT pay $1000, i promise you can get the exact same result with a little TLC of your own
