Thank you SO much for this info and your above posts too... I've been trying to lock down a BALLpark of what this "uber expensive" implant would cost and FINALLY found your recent post! I have yet to determine if the ONE avian vet in our area will even do so- as I wasn't sure it was a road I could go down yet- but will now check to see!
Had been in touch with one other person in the UK who had great luck with this recently and like yours in the past was lucky to have it start just prior to the winter months so stopped laying naturally but came back in this spring!
Like you, I'm only worried about her quality of life. Thus far that's been dependent on my treatment of the resultant symptoms/problems from internal laying... Which she's responded to really nicely but every week brings a few days again where I can tell she just doesn't quite seem herself-at least until they're let out of run for in the afternoon and even then, she's more "strolling" than foraging with zeal! ;-)
But she seems happy out in the yard! Problem is we have a real "hawk alley" thru our property and they are VERY active- esp in the am...so going thru a hawk attack is NOT on my wish list... so we try to at least compromise and minimize the risk...
Boy I wish I was still completely ignorant to this entire issue (kidding- but it sucks to know what I'm in store for most likely with my others- one of whom we already lost- she never even really laid so likely really had some internal reproductive issues- perhaps neoplasia's) of internal laying and crop issues with these chickens that were sadly bred to lay, lay, lay!! I've been BLOWN away by what I've read over the last couple months- that we've gone from an avg of 16-maybe 20/yr from their original ancestor- the jungle fowl- to an avg (from memory here ;-) so forgive me if I'm off a bit) of around 120/yr in the early 1900's from a "farm" chicken.... to now having so many of them avg 300 eggs/year!!! That has been purposefully bred into them and boy I feel guilty for being so clueless that we participated in this by picking up a total of 8 (2-foursomes) adorable chicks from TSC that my DH brought home after we started to really talk about using the coop/run that came with our new home....
But I guess we are absolved of that initial ignorance but will DEF work much harder to find a responsible reputable breeder for any more chickens we 'adopt' (I say as they're mostly pets- who used to come with an insane amt of eggs as a bonus) but now I realize that was just for really those first 2-2 1/2 yrs... our troubles came after that first molt their second fall/winter.
BUT truly- thanks again!! Praying for your little Thanos... think she was far more stressed by the whole "adventure" as you pointed out- than the actual injection. Yeah, a 16Ga needle is pretty big but he even used some lidocaine! pretty nice ;-) (problem as a human at least is that they SO often don't wait long enough to give that a couple MINUTES to even work first! just do it and then dive in!)
But my hen tolerated about 5 injections total (though with a 22Ga) into the same area between the wings on back/base of neck without even reacting really at all- was far more upset about being picked up and held than eventually getting her abx SQ injection- did great. What you described sounds like every other description of the procedure I've read down to the glue!
God Bless! Will def. look for any updates!!
