Being a first-time chicken owner I could make a list of "Thank yous" for all the help you folks have been to me already, so let's just suffice it to say thank you all for being you and for being here with answers to all of my questions before they're even asked! I have 3 RIR and 2 Leghorns who are of laying age and am enjoying 5 eggs almost every day (started out with 8 but my dog got 3 a couple weeks ago) We didn't want just 5, so my son added 6 chicks to our count; then a neighbor 'dropped off' 9. Now I have Black Alstrlorps, Golden sex-links, Buff Orpingtons, more leghorns and my pre-existing 5! I see some building and more innovation in my very near future. I'm sure caring for 20 won't be the same as caring for 8 was. One concern I have is that a reliable source recently told me that I should "never" introduce the little ones to the bigger ones, as there is potential danger there and I'd have to constantly watch them. Does anyone with experience have thoughts on this? Ideas on how to intermingle them safely?
