As incredible as it may seem, my area of town ran out of chick starter crumble. I called all the pet stores around me and none of them carried the brand that I originally fed the chicks. I even called the distributor. I tried switching the girls to mash, but they refused to eat it. In fact there wasn't any poop for 2 days. I added water to their mash. I mixed in lactose free yogurt into it and they refused to eat. One of them ran towards me and yelled--what I believe to be chicken obscenities-- at me. I bought layer feed that looked most like the crumble that I had initially fed them. And the next morning there was the biggest pile of poop on the planet! I know that I have to change their food back to the chick starter, but I'm concerned that the girls are going to refuse to eat again. Can I safely assume that mixing the chick starter with the current feed would ease them back into eating the chick starter?
