# Chick placement (Bird Purchase)
> Record day-old chicks placed on a farm — the start of every flock's data.
A **Bird Purchase** records the day-old chicks placed on a farm. It's the transaction that actually starts a flock: it sets the batch's **opening bird count** and **first-day weight**, which every later calculation (mortality %, FCR, GC) builds on.
Create the batch first ([Creating a batch](/farmers-batches/creating-batches)), then record the placement here. One bird purchase per batch is normal — GrowTak warns you if a batch already has one.
## Recording a placement
Go to the **Bird Purchase** screen and select **New**.
| Field | Notes |
| -------------------------- | ----------------------------------------------------------------------------------------- |
| **Farmer / Batch** | The batch receiving the chicks. |
| **Date** | The placement date. |
| **Hatchery** | The supplier the chicks came from. You can create a new supplier inline. |
| **Reference No.** | Invoice/order number. |
| **Flock Code** | The hatchery's flock identifier from the chick certificate. |
| **First Day Chick Weight** | Average chick weight at day 1, in **grams**. Important for accurate weight-gain tracking. |
| **DC Number** | Delivery challan number. |
| **Status** | Leave as **Completed**. |
| **Remark** | Optional. |
**Line item:**
| Column | Notes |
| ---------------- | ----------------------------------- |
| **Product** | The bird product (e.g. *Cobb 480*). |
| **Unit** | Usually *Number*. |
| **No. of Birds** | The quantity of chicks placed. |
| **Rate** | Cost per chick. |
| **Amount** | Calculated automatically. |
Select **Create**. The batch now has its opening stock of birds.
## What this sets up
* **Opening bird count** — the baseline for mortality and "remaining birds".
* **First-day weight & flock code** — recorded against the batch.
* **Chick cost** — feeds the cost breakdown used at GC time.
Double-check the **No. of Birds** and **First Day Chick Weight** — these two numbers underpin every performance figure for the batch.
## Browsing placements
The list shows each placement with farmer, date, reference, flock code, first-day weight, hatchery, products, bird count, total quantity, amount, and status. Filter by hatchery, batch, or date range.
