Yes, then don't try getting it down his throat. And a previous poster suggested the tube feeding method if you ever have to get something down the throat & I agree that's the best way.Thanks for the method, I will copy it down in case I need it later on but I was trying to give him yoghurt via syringe into the beak (little bits into the side of the beak so he could swallow himself) but he kept trying to close his beak. I think i'd probably end up getting it down his windpipe by accident.
Besides all of the other chatter, mine included, I don't really think he needs anything at this point. I just think that he's just being a good provider & letting his girls eat first. Keep an eye on him, monitor his weight, see & if that crop empties & refills. I am sure that you will find him to be just fine. If not, there's a lot of help on here.
