I'm not sure. Their tails try to convince you that they are roos. Their comb size may mean they are roos too, but it might just be the breed. I have a hen with a LARGE tail and when I say large, I mean it.
Dust baths are supposed to suffocate mites. If you want to add extra stuff, add diatomaceous dirt (a chemical, so you might not like it), lavender, or some other herbs. Ashes from fires are also good for them.
Leave them be. If you are sure they can't get out you can carefully, with tweezers, snap off tiny pieces of the egg around the hole. REMEMBER, ONLY DO THIS IF THE BIRD CANNOT GET OUT!
Not true. You could feather sex them, but that only works for some breeds. 007Sean can tell you. Good for you getting chickens! :weeBut be prepared to lose one of them. One of mine was killed by a hawk. :barnie:hit:he:( They are still 110% CUTE! I think they are males. A hen's tail isn't that...
