I have 3 chickens that 3.5 mo. old. Here's my questions. When do they start laying eggs? What kind of hay do I need to use for them to lay. Does the laying box need a lip on the edge? And 2 don't hardly have a comb or wattle and one does. But the one I was sure was a hen is super aggressive. First she'd rather eat out of my hand than off the ground and in the process tries to take off a finger. If my dog comes near the food she's eating she goes after the dog and tries to claw her face off. (which I might add is downright hilarious since my dog is a 70 lb. boxer) She follows me everywhere and is fearless. So she seems more like roosters i've heard of. But she has no wattle or comb. (barnyard mixes btw). The americauna mix appears to be a hen and nervous but placid. Then there's the barred rock mix (I think) And he has a comb and wattle, but this guy is the biggest chicken ever (no pun intended). He hides from everyone and when the other two come out to eat, he watches from under the deck and darts out to get a few bites before hiding again. He's not remotely aggressive or alert. And if he gets separated from the other two he just cries and cries. So am I confused on the sex? Or can hens be that dominant and roos that submissive? Oh and the other thing is they like to hang out under the deck...is that normal? I'm worried they'll start laying down there and I won't know. Thanks in advance!
