I currently have 8 chickens- 2 roosters for 6 hens all a year old this spring. My hens are pretty well "loved" by my roos so I do need more hens (too much of a softee to send one of the big guys to the freezer and don't know where to rehome him to) Current coop is 60 sq ft. Run is getting redone in the spring and the flock free ranges 5+days a week anyhow. I want to get as many chicks as possible to minimize the stress of adding new ones- I'm thinking 5 but is 6 too many? Spring-fall is no issue I just worry about the Wisconsin winters and them all being stuck inside for 3+ months. Also my current flock is 4xBR 1 RIR 1 Manas roos are both 10lbs 1xEE and 1xJG. I want easter egger chicks is it going to be an issue that they're only 5 lbs to my big girls' 7ish pounds? Will they have issues acclimting because they'll never be the same size?
