You guys probably already thought of this, but in the off chance that you didn't, this is what I discovered today. I was trying to entice my sickish Black Japanese chick to eat some plain yogurt this morning to help his poop situation, and he refused to do anything besides peep. lol So, I put yogurt in a dish and sprinkled starter on it. Still no luck. They all looked at it like it was alien food.
Then a Sebright ran right through it, ornery little things, and it stuck between his toes. As soon as I saw that, a light came on, and I watched him.
Sure enough, he didn't like the feeling of it on there, so he stopped and started pecking the yogurt off of his toes. Every time he pecked at it, he ATE it!! The other chicks started running through the yogurt and getting their feet sticky, and they all ate it too. Including my Black Japanese.
The Sultan bantams got a little grody, with their super feathery feet, but they managed to clean it all off, too.
So, maybe the next time you have chicks refusing yogurt because of it's odd texture, you can try to use it to it's advantage! lol
