I have four young hens that began laying one month ago. I have seen 3 lay regularly but the fourth I havent seen lay at all. For the last couple of weeks she has been flitting around the coop like a mad thing but she has been eating and drinking well. Im not sure if she scares from shadows or what. The last two days she hasnt come outside at all after the inital release in the morning at which she eats little and drinks little, she then goes back inside preferring to sit on the floor of the henhouse. The past two days the hens have been on Tetravet as two of the other ones were unwell but seem back to normal now. Could this have made her feel a bit off or could she be eggbound? Any help would be appreciated. Thanks.
