I think it goes like this, with two sets of chicks:
sammie12345 got two white chicks at Tractor Supply more than 4 months ago. The chicks were said to be White Rocks. The chicks were given free feed until they started acting unhealthy (laying down to eat, for example.) After that, the chicks were limit fed, and seem more active and healthier. People on this thread are questioning whether those white chicks might be Cornish Cross, even though Tractor Supply called them White Rocks.
sammie12345 is now planning to get 2 more chicks, Rhode Island Red this time. Because of the previous experience, he/she is planning to limit-feed the new chicks, and wants to know how much food is appropriate.
This thread has wandered back and forth talking about both sets, and about chicken-feeding in general.
@sammie12345 Do I have all that right?
