Does Ivermentin make them sterile??

[MakNat]

Does it make the hens, roos or both sterile?? I'v heard that but i'm not sure and if anyone knows who or which ones and how long, please let me know!! I'm talking about the pour on cattle kind used to worm chickens with a drop on their necks! Thanks

The info I read was that it was a possible side effect in a small percentage of uses and even then the effect was temporary. I used it on a BO pullet a few weeks ago and she started to lay right on schedule.

I am pretty sure that ivermectin is ivermectin (doesn't matter what form). I use the injectible for cow/swine I drop 0.25cc down their throats and it is done. I have never had a problem so far. Works great too.

never had a problem here and have used it for years

Used it just a few weeks ago. My hens are laying like crazy. I haven't checked the eggs for fertileness lately, but I doubt old Thor is having any problems in that dept.
