Hi everyone! It will soon be a full year that I have had chickens, and I really have enjoyed it. Although, this winter has been really rough. How better to celebrate the new coming spring with… baby chicks! Right? So I need some help here. I have four chickens. A big BO rooster, Edith; a Buff Brahma hen, Mary (both of which I raised as chicks); I also have an EE hen and RIR hen that I bought this fall as pullets. My run is about six by seven feet (or 42 square feet). The coop floor is 3 1/2 feet by six feet, and there is an upper platform that is 3 1/2 feet by 3 feet that they can fly up onto. Since we just finished this "winter proof" coop right before the snow started, we didn't have time to expand our run (but we plan on expanding it quite a bit in the spring/summer). There is a portion about 3ft by 6ft of the coop that I am currently using for storage but could easily cover in pine shavings for more chicken space. I also have an A-Frame coop that is currently not in use that I could raise any new chickens in until they reached a good age to integrate. Am I crazy? I want to know if getting more chicks would be harmful to my current chickens, that way I can stop this silly dream in its tracks. If you don't think I'm a nutcase, how many would I be able to get? The other thing is that my current hens have bare patches on their backs from my rooster mating. Would getting more hens solve that problem? Or just lead to other issues that I haven't even thought of yet? Also, one last thing. My Buff Brahma hen had a strange respiratory illness back in December. None of my other chickens were affected in any way, but her eyes were watery and she sneezed a lot. I gave her doses of Baytril as ordered by our vet and she has been perfect ever since. Would this affect anything? Thanks everyone!
