MY bantams and ducks arent laying???

[TayFray!]

I just got 3 mallards (2 males. 1 female) and 4 bantam chickens (3 hens, 1 rooster) They were laying before i got them and now they aren't. The mallard has laid one egg when i first got her, the bantams have laid 2 since ive gotten them, but nothing lately. They have been eating and drinking and everything. I got them on april 16th!

Please help me!
