Since you asked for general care information, a 6X4 foot coop is too small for 5 chickens, and especially 7 chickens, unless they free range during the day. Technically, yes, people say that chickens only need 2-3 square feet per bird, but realistically that's miserably crowded -- especially with 2 cocks to continuously bother the hens. Most breeds need a 1:5 or greater ratio of males to females (there are a few exceptions). If you're going to have 2 cocks with 5 hens, which I have in an old flock that I inherited that came as a bonded family unit when it was 6 months old, the hens need to have hen saddles. I didn't know that the first year, and the poor hens had all the feathers on their backs and wings scratched out as the males tried to breed, and then without feathers they got wounds and then terribly sunburned, so they were constantly painful as the males continued to breed them. When I got the hen saddles, the skin was protected, so everything healed and the feathers grew back. They're 7 years old now, huge Croad Langshans, arthritic and on pain meds, but the hen saddles and free ranging has kept them comfortable and happy, even though there is still one more rooster than there should be. Here is the company that I bought my hen saddles (also called a hen apron) from: http://hensaver.org/ I would recommend getting the shoulder protectors also to go with them, as the shoulders get terribly injured without them.
Thanks for the very useful information, My chickies free roam all day dawn to dusk, they only go in their coop at night and immediately take up their position on the perch. I will take your advice on getting saddles for my girls as the Red Cochin is already trying with her even tho' she is only 15 weeks old and hasn't laid her first egg yet.
