I am very new to the chicken world.....in fact, a friend is giving me 5 ....3 hens and 2 roosters Delawares and Welsummers....My question is to get the chicks my Hubby has to build a coop...We areplanning on getting at least 10-11 more hens.....so do we build small for the 5 and then add on or build a bigger one anticipating more hens.....any information ius so appreciated.....I am so very excited and a litte nervous...Oh and one more thing bears, coyotes, raccoons, snakes etc etc....We do have them here and I was wondering how do you keep one from destroying your pen? any ideas...?????
