I have a RIR hen that I let sit on 4 eggs. Well on day 19 the first chick hatched and she peck it and threw it from the nest to the coop floor and it died. The next morning #2 hatched and she did the same to this one. I got #3 as it hatched and have it in a brooder under a light at 95 degrees. The hen is now sitting on #4 egg. I checked this egg and felt the chick inside moving so I will be very vigilant and take it from her as soon as it hatches. The one I have in the brooder now seems strong and is eating and drinking water on it's first day. But it has a flesh wound on the back of its neck. Should I and can I treat the wound? All help is greatly appreciated. Thanks in advance, Rich.
