Okay so I have found a breeder (my vet said breeder is good, and we live in a small town). Am planning to get 3 chicks, ideally 2 hens and a rooster. I asked my lawn man to quote me on building a small coop and fencing the run (will be a nice size for 3 chickens, 25' x 25' run plus the plan is they can free range the big field part of the day). So anyways lawnman says he also has a chicken that he needs to "get rid of". He has a bunch of RIR's and someone gave him hen that lays green eggs (he didn't know the breed), poor girl was stuck in a 2' x 2' pen and outgrew it so they gave it to my lawnman. He put the hen in with his RIR's and now he believes she is eating eggs. Lawn man is a "good ole' boy", retired welder, vietnam vet, redneck, hunter etc... Great at building stuff but not the most "sensitive" regarding animals. I am sure we can work out the evil egg eating problem (if in fact it is a problem). He says the hen is sweet. I am buying chicks from a closed flock fanatical breeder so do I need to worry about disease? Would a single hen be likely to torment 6 weeks old chicks? Somehow I think she won't. Should I have my vet check the hen out for mites? If I got her before I was ready to let the chicks into the pen would having a single adult chicken cause emotional problems due to isolation? Should I wait until I can introduce them all at once? Chicks and hen at the same time?
