I've got a flock of Rhode Island Reds. Half of them are 8 months old. The other half are 5 weeks old. I want to get new feeders. The ones I'm looking at are 7.75 inches tall. The hens have met the chicks, but are separated by chicken wire. I was planning on integrating the flock at about 8 weeks. But, I'm wondering if the chicks will be tall enough to use the new feeders or if I should create a feeding area, for the chicks that they can reach, but the hens can't.
