I got chicks last Thur that were a few days old and have been using the horizontal poultry nipples. My trouble is they will drink out of the nipple when I activate it and get the water to rest in the little cup area but they are not getting how to activate it themselves. I have tried tapping...
I have seen a great treatment plan on Chicken Chick's website: http://www.the-chicken-chick.com/2012/02/spraddle-leg-in-baby-chicks-what-is-it.html
I just got chicks last week so I'm by no means an expert but I bookmarked her page in case this happened to any of mine. I hope this helps.
