Hello. I am new here. Its been awhile since ive owned chicks. My husband and i built our first coop before we bought our babies. We got them the friday of easter. They didnt know how old they were or what sex they were. We ended up with 6 white leg horns. All very sweet and cuddly. Weve had them almost 3 weeks. Most of their down is gone except for on their heads and a little under belly. Well i think we may have picked 5 pullets and one roo. Not sure yet. The chick in the back is the one in question. I thought i picked all female by wings but a friend said she looks like a male because the comb is a little bigger than the other 5. I am letting them out to play during the day in the coop, but they are inside in our living room in a cage at night and when we arent home. We have 4 dogs. One shepherd heeler mix who has already busted the chicken wire and dug a hole and broke one latch on the bottom of the door. Any suggestions on keeping her out? Shes getting in when the chicks arent even in the coop and run. We made a 10 ft enclosed run for them and a coop with two boxes. We only planned on getting 3 but had to get 6. Here is the coop and run.
