Hi, I have 7 hens that are 9 weeks old. 6 Buff Orpingtons and 1 Barred Plymouth Rock. We were supposed to have 9 hens, but 2 ended up being roosters! So question #1: One of the Buffs broke the tip of her upper beak off. It was dangling there, and then my boyfriend was going to trim it off, and it broke off by itself when she pulled back from the clippers. Then, a few hours later, the tip had a scab over it! She can still eat and drink perfectly normal! I've hand-fed her, and watched her get drinks. Should I do anything to it, or leave it alone? Second question: If I have a broody hen, can I put food/water in or right outside the nest box so she doesn't starve herself? Third question: I don't want anymore chickens this year. How can I stop my roosters from fertilizing eggs? 4: How can I get them to go into the cooo if I need them to all go inside for some reason, like fixing the run, the neighbors loose dog outside the run, etc? Thank you! If you can answer even one of my questions, I would appreciate it!
