our chicks are approaching the 5 week mark, and all but 2 are doing great. one is still about the size they were at 2 weeks, but is surviving and seems healthy, except not growing. the one I am asking about is having a hard time walking, and with 3 weeks to go, i am not sure what to do? would putting it in a separate area and cutting the food back on it be the answer? we take the food away at night , and they probably run out about 10pm until 7. i will start having them run out about 8pm until 7, altho, the rest are up and around, I don't want anymore to get too heavy to walk.
